Applied Mechanics Meetings and Track News from the Technical Committees
Introduction to the Applied Mechanics Division: The Applied Mechanics Division (AMD) is one of the oldest and largest divisions of ASME. Professor Stephen P. Timoshenko, first Chairman of the division, and others founded the Division. The main goals of the AMD revolve around the dissemination of mechanics research results and the stewardship of the society in matters of applied mechanics. The aims of the AMD are twofold: to foster fundamental research in mechanics, and to ensure intelligent application of mechanics. Mechanics is a scientific discipline that studies causes and effects of mechanical phenomena. Such phenomena of lasting interest include flow of fluids, deformation and fracture of materials, diffusion of molecules, instabilities of plates and shells, and propagation of waves. Applications of mechanics are intimately tied to the contemporary needs of society. Examples include design of cars, aircrafts, ships and buildings; functions of biomolecules, cells and organs; and durability of medical implants and silicon chips. While these phenomena and applications overlap with the fields of interest of many other divisions of the ASME, the AMD is primarily concerned with methods and approaches that yield a high level of understanding and systematically apply the principles of mechanics. The AMD embraces all approaches to mechanics: theoretical, experimental, and computational. It complements the activities of other divisions and cooperates in joint endeavors.
AMD Activities: A main focus of AMD activities is the dissemination of technical results generated by its members and the broader world‐wide applied mechanics community. The AMD organizes meetings for the presentation and discussion of research in its field,
2
provides opportunities for the publication of such work, and in various ways, cooperates with other organizations having similar interests. The AMD, through its technical committee structure, organizes the applied mechanics sessions at the International Mechanical Engineering Congress and Exposition (IMECE), by programming the symposia and committee meetings of the AMD and by scheduling its Annual Honors and Awards Banquet. This meeting occurs in November of each year.
The AMD is also involved in a series of applied mechanics summer meetings. The AMD participates annually in the summer series by programming symposia and committee meetings. A four‐year rotation is used to determine the principal organizers of the summer meetings, as described below.
• Year 4n (2012, 2016, etc.): International Union of Theoretical and Applied Mechanics organizes the International Congress of Theoretical and Applied Mechanics. The AMD supports this activity through the US National Committee on Theoretical and Applied Mechanics.
• Year 4n + 1 (2013, 2017, etc.): The AMD organizes a meeting jointly with the Materials Division of the ASME, the Engineering Mechanics Division of the American Society of Civil Engineers, and the Society of Engineering Sciences. The principal role alternates between the AMD, the Materials Division and the Engineering Mechanics Division of ASCE.
• Year 4n + 2 (2010, 2014, etc.): The US National Committee of Theoretical and Applied Mechanics organizes the US National Congress of Theoretical and Applied Mechanics. The AMD supports this activity through symposia.
• Year 4n + 3 (2011, 2015, etc.): The AMD organizes a summer meeting jointly with the Materials Division of ASME. The principal role alternates between the AMD and the Materials Division.
The location and timing of these meetings is determined a year or two ahead by the primary organizing group. AMD members are encouraged to participate in all of these venues by submitting papers, attending and organizing symposia.
This June, the 2009 Joint ASCE‐ASME‐SES Conference on Mechanics and Materials (MECH 09) was held at Virginia Tech in Blacksburg, Virginia. The meeting was organized by Professor Ishwar Puri and Professor Muhammad Hajj of the Engineering Science and Mechanics Department at Virginia Tech. Over 600 abstracts were submitted and the meeting was very well attended by 404 delegates from a total of 27 different countries.
In terms of print, the AMD is custodian of both the ASME Journal of Applied Mechanics and the journal, Applied Mechanics Reviews. The Journal of Applied Mechanics is edited by Prof. Robert M. McMeeking of the University of California, Santa Barbara. Applied Mechanics Reviews is edited by Prof. J. N. Reddy of Texas A&M University. Both journals only accept submissions electronically and both can be reached through the main ASME web page by choosing publications. I encourage you to review for these journals when asked to, as the journals maintain high quality and this is a very valuable way to contribute to the Division.

2008 IMECE Meeting: The 2008 IMECE winter meeting was organized by Professor Tayfun Tezduyar of Rice University, and incoming Vice Chair of the AMD Executive Committee, and was held in Boston, MA, November 2‐7, 2008. This was the second year of the reorganized conference under what is known as the “track” system. The AMD conference was very successful using this new system with 35 symposia, 100 sessions, and 500 papers, thanks to the efforts of Tayfun and the AMD Technical Committee Chairs.
The Applied Mechanics Division Honors and Awards Banquet was held in Boston on Tuesday, November 4, 2008 (yes, election day) during the 2008 International Mechanical Engineering Congress and Exposition. This banquet represents a signature event of the Applied Mechanics community. The AMD administers three Division Level Awards – the Thomas K. Caughey Dynamics Award, the Ted Belytschko Applied Mechanics Award, and the Thomas J.R. Hughes Young Investigator Award ‐ and three Society Level Awards – the Drucker Medal, the Koiter Medal, and the Timoshenko Medal.
Professor Ali Nayfeh of Virginia Tech was the recipient of the Thomas K. Caughey Dynamics Award, “for his seminal analytical and experimental contributions to nonlinear dynamics and structural mechanics.” Dr. Chad M. Landis of the University of Texas at Austin was the recipient of the Thomas J.R. Hughes Young Investigator Award, “for his outstanding contributions to the mechanics of active materials.” Professor Choon Fong Shih, President, National University of Singapore and Founding President, King Abdullah University of Science and Technology, was the recipient of the Ted Belytschko Applied Mechanics Award, “for lasting contributions to mechanics, and for building bridges between disciplines and between nations”.
The Daniel C. Drucker Medal was presented to Thomas C.T. Ting, Professor Emeritus, the University of Illinois at Chicago, and Consulting Professor, Stanford University, “for significant contributions to the development of the Stroh formalism of anisotropic elasticity, and to the analyses of several fundamental inelastic and wave propagation problems.” The Koiter Medal was awarded to Richard D. James, Russell J. Penrose Professor, the University of Minnesota, for “pioneering the modern vision of phase transformations and materials instabilities in solids.” Professor James also delivered his Koiter Medalist Lecture just prior to the banquet. The Timoshenko Medal was given to Sia Nemat‐Nasser, Distinguished Professor of Mechanics and Materials, The University of California, San Diego, for “fundamental theoretical and experimental contributions in: dynamic stability; deformation and failure modes of materials; nano‐electro‐chemo‐mechanical characterization and modeling of ionic polymer metal composites; and composites with integrated tuned electromagnetic functionality, self‐healing, and self‐sensing.”
During this event, newly elected Fellows of ASME were also recognized. In addition, the American Academy of Mechanics presented its awards, and new and outgoing Associate Editors of the Journal of Applied Mechanics were recognized.
2009 IMECE Meeting: The 2009 IMECE winter meeting will be held in Lake Buena Vista, Florida (http://www.asmeconferences.org/Congress09/) from November 13‐19, 2009, and has been organized by Professor Ares Rosakis of Caltech. Ares is the incoming
4
Program Chair of the AMD Executive Committee. In addition to the technical meetings, the AMD will hold its annual Awards Banquet, and all are encouraged to attend this festive event.
The recipients of the 2009 awards have been announced on the ASME website, and are listed here: Pradeep Sharma, University of Houston, will receive the Thomas J.R.

TIMOSHENKO MEDAL Sia NematNasser
The Timoshenko Medal was established in 1957 and is conferred annually in recognition of distinguished contributions to the field of applied mechanics. Instituted by the Applied Mechanics Division, it honors Stephen P. Timoshenko, world renowned authority in the field, and it commemorates his contributions as author and teacher. The 2008 Timoshenko Medal was awarded to
Professor Sia Nemat‐Nasser, Distinguished Professor of Mechanics and Materials at the University of California, San Diego, for fundamental theoretical and experimental contributions in: dynamic stability; deformation and failure modes of materials; nanoelectrochemomechanical characterization and modeling of ionic polymer metal composites; and composites with integrated tuned electromagnetic functionality, selfhealing, and selfsensing. The acceptance speech was presented at the Applied Mechanics Dinner of the 2008 Winter Annual Meeting of the ASME, on Tuesday, November 4, 2008, in the evening of the Election Day of the United States of America. Before I start, let me mention my wife, Eva’s contribution to this lecture. She said to me to make a draft first and then she would be happy to help me to tighten it up later on. After a day and half’s work, I took the result to her who quickly informed me that: it was much too long, contained too much unnecessary details, and that, it can be reduced by 3/4th without losing anything significant!
After another several hours of effort, I took the product to her who immediately requested further reduction, by at least a factor of two!
This process went on for a few cycles when, finally, she said: “if you cut it in half, then it might be OK.”
I did.
She looked at it and asked me to read it out loud.
I read: ‘Ladies and gentlemen, and the Timoshenko Medal Committee, thank you very much.’
“Now, that is a good after dinner speech”, she shouted.
Then she thought for a minute and said: “You Persians are very wordy. If you leave out the ‘very much’, and just say ‘thank you’ then it would be a great after dinner speech!”

Timoshenko Medal Lecture
A MechanicsGuided Journey through Engineering Science
I wish to first thank our gracious MC, Professor Dan Inman, for his generous introduction. I would also like to thank you, ladies and gentlemen, for being here tonight, after several arduous political weeks of having repeatedly heard from Joe the Established Politician, Joe the Unlicensed Plumber, and Jack the Unknown Electrician, just to mention a few, to hear from Sia, the also Unlicensed Mechanician.
I am indeed, thrilled and honored to have been chosen as the 2008 Timoshenko Medalist, and wish to thank the Timoshenko Medal Committee for, at least from my point of view, a pretty good choice!
I have admired Timoshenko and the impact of his remarkable teaching through his books, since I was an undergraduate student and, later, as a graduate student, having managed to purchase and study essentially all of them, which I still possess and often use.
As for tonight, I am amazed that you, ladies and gentlemen, have chosen to be here, listening to me, rather than being glued to the television, hopping from the Situation Room of Wolf Blitzer, to Mark Shields, David Brooks, and Jim Lehrer’s more philosophical pontification, or, I hope quite unlikely, Fox News’ Sean Hannity and his profoundly intellectual colleagues.
As for the presidential candidates, while I have rooted for Obama, and I have been proudly wearing an Obama‐Biden button, I also purchased, just before coming to Boston, a McCain banner, in case all the polls turn out to be incorrect.
In either case, truly, one should wonder why two exceptionally talented individuals would want to compete so hard for so long and with such passion, for the opportunity to inherit:
Two unwinnable wars,
A crumbled economy, and
The leadership of a turbulent, hostile, and unstable world politics and economy, instead of sipping wine and contemplating about life. And, more interestingly, it is mind‐boggling why we, a bunch of intelligent people, so enthusiastically cheer them on in their misguided journey, and even put down our hard‐earned money to help them succeed in their ill‐chosen quest.
Putting aside the mundane issues of war and peace, potential economic bankruptcy, and the collapse of the world politics, let me now focus on the main purpose that has given me the privilege of addressing you, ladies and gentlemen.
Being honored by this prestigious medal, late in one’s professional life, has its advantages and disadvantages. One advantage is a long professional experience with a rich supply of anecdotes to share.
7
The disadvantage, however is that one would know that one should not overdo it, as we have been reminded by many of the previous recipients of John Hutchinson’s famous advice to his distinguished colleague, Bernie Budiansky, after having introduced him, saying, “Bernie, keep it short.”
What many of you may not have heard is my own unique experience with John: when I first heard that John would be receiving the Timoshenko Medal, I wrote a congratulatory email to him, and, in passing, reminded him of his advice to Bernie, in San Francisco, in a Chinese Restaurant, to keep it short. John immediately wrote back, thanking me, and, at the same time informing me that he does not practice what he expects others to do.
Tonight, however, I should try very hard to do what John does not do, yet expects me to do.
2008 has been a significant year for me. It marks 50 years since I stepped on American soil, on June 23, 1958, as an undergraduate student, with $200 worth of American Express checks in my pocket and a great deal of hope in my heart. Remarkably, the Timoshenko Medal which was established in 1957, with Timoshenko being the first recipient, was given to three giants of our field, Arpad Nadai, Geoffrey Taylor, and Theodore von Karman, in 1958.
The journey to the US was preceded by many events that, in retrospect, make me realize how lucky I have been to have survived through them all. And this, I mean, literally. My high school years, as well as my 2 years at Teheran University, were filled with political turmoil with unpredictable consequences, as I had been present within crowds when, once the dust had settled, at least a few bodies journeyed to the morgue.
In the halls of the engineering school at Teheran University, for example, the marble columns featured repaired bullet holes, witnessing an event that just a few years earlier took the lives of 2 engineering students. Even, under those conditions, I continued to be lucky, enjoying the respect and undeserved attention of colleagues and professors, as the top student of the school of engineering.
Nevertheless, I had decided to try my luck in the United States, even though I lacked the financial means. The story that took me to Sacramento and hence, Sacramento State (then) College, and later, to Berkeley, also involved numerous unexpected events which only my good luck had produced favorable results, although my academic record also helped. In addition to well‐paying part‐time work in civil engineering firms in Sacramento, which I frequented every summer and during holiday vacations, there was ample financial support in the form of forgivable loans, fellowships and rather light teaching assistantships.
The intellectual life at Berkeley was, indeed, rich and exciting. I had the good fortune to know some of the most distinguished mechanicians of the time, and participate in the excitement of the new wave of more fundamentally‐based structural mechanics and structural engineering.
Unquestionably, this trend emerged because of Timoshenko’s influence. While I did purchase and study all the black‐covered books of Timoshenko, I did also carefully study
8
his red‐covered advanced strength of materials book which I still possess and occasionally consult.
The next stroke of good luck was when I met George Herrmann who came to Berkeley to present a seminar. My advisor, Colin Brown, in passing, suggested that I should talk with Professor Herrmann who was then looking for a post‐doc.
A trip to the library taught me that Northwestern University was located in Evanston, Illinois, with the largest number of churches per capita in the United States. Assuming that George may not like my goatee, a rather unusual facial feature at the time and associated with Berkeley activists, I shaved my beard before the interview, being rather amazed that George had noticed it before, and asked me why I had shaved off my beard and that it actually looked good on me. I simply said, “If you give me the position, I will grow it back”. He did and I did.
The departure from Berkeley in the summer of 1964 occurred in the wake of Mario Savio’s four‐letter‐word free‐speech movement, which arguably marked a new chapter in the culture of the United States.
The intellectual life at Northwestern was vibrant and remarkably enriching. It was there that I not only had the good fortune of meeting Eva, and with her creating a new chapter in our family life, but also, I met and made life‐long friends with some of the most intelligent and creative applied mechanicians of our generation, several of whom have already been honored by the Timoshenko and other ASME medals.
The impact of Sputnik had been driving graduate education and research in engineering and creating a tumultuous environment for new positions at various universities, with essentially guaranteed research funding. I was recruited by Bill Prager to join the newly established Department of Aerospace and Mechanical Engineering Sciences (AMES) at UCSD, while, at the same time being courted by several other universities.
The final decision was easy to make, once I visited La Jolla, during a cold spell in Chicago, walked by the ocean, and realized the position will give me an opportunity to be a colleague of luminaries, such as Bert Fung, John Miles, Sol Penner, and many others in the department, as well as more than half‐a‐dozen Nobel Laureates, on a university faculty of 275.
Even so, Governor Reagan’s rather less than friendly attitude toward the University of California, the Regents’ hostility toward Herbert Marcuse, Angela Davis, and the Nobel Laureate, Linus Pauling, produced a situation that drove Bill Prager back to Brown, and me back to Northwestern, where I had the opportunity to work with my contemporary young colleagues and friends, while the growth at UCSD had been basically stopped.
It was during my 15 years at Northwestern that, I feel, my scientific growth took place, in major part because of close association and collaboration with colleagues, such as John Dundurs, Toshio Mura, Jan Achenbach, Leon Keer, Zdenek Bazant, and, later on, Ted Belytschko, not to mention more established luminaries, such as Hans and Julia Weertman, as well as Morrie Fine.

There, I had the opportunity to move into new areas, such as soil mechanics in relation to earthquake‐induced liquefaction, rock failure and fracturing in relation to hot dry‐rock geothermal energy, and the mechanics of frictional granules, just because it was fascinating. Timoshenko’s teaching that embodied the application of rigorous mechanics principles, the necessary applied mathematics, and a great deal of intuitive physical insight, was indeed the key to most of my contributions.
I also enjoyed having some very outstanding coworkers and graduate students such as Monte Mehrabadi, Minoru Taya, Tetsuo Iwakuma, Hideyuki Horii, Makoto Obata, and Muneo Hori, as well as a number of outstanding Japanese visitors and post‐docs, thanks to Toshio Mura who provided the bridge between Northwestern and the Japanese mechanics community.
My work on liquefaction that aimed at understanding the basic phenomenon through mechanics‐based mathematical modeling, supported by my own and others’ laboratory experiments, has since been used extensively, not only to understand laboratory results, but also actually, to assess site potentials for liquefaction in actual field applications. Yet, at the time, it took quite a bit of doing to get the paper published in a geotechnical journal. I am pleased to see that we have come a long way, not least thanks to Timoshenko and his influence.
One fact, I learned early on, was the necessity of simple experiments to support mathematical modeling. I followed this all through out my tenure at Northwestern University, beginning with some cute yet intriguing experiments on flutter, with George Herrmann, and then model experiments to show compression‐induced axial splitting, faulting, and transition from brittle to ductile failure of brittle materials such as rock and concrete.
In this case, my graduate student, Horii, and I did a number of convincing experiments on models made out of a brittle polymer, using a large vise in our group’s top technician, John Schmidt’s lab. Remarkably, the idea to do such model experiments came when my young colleague, John Rudnicki, commented on my work with Horii, on tensile crack growth under compression, a completely mathematical exercise, using Muskhelishvili’s complex potentials and some elaborate calculations. John simply said: “It’s interesting, but you will have a hard time to convince geophysicists and rock mechanicians.”
The analysis that followed and a sequence of model experiments, some quantitative, resulted in 3 papers that have since served as a basis for understanding brittle fracturing under compression.
As I look around the country and even worldwide at our community, I see many applied mechanicians of my generation have successfully moved into new fields, be it earthquake prediction, macro‐molecules, biomechanics, or genetics, and guided by the culture that is rooted in Timoshenko’s teaching, managed to open new horizons in engineering science.
In my own case, when I returned to UCSD in 1985, the then fertile environment allowed the creation of an integrated campus‐wide materials science program that brought colleagues from physics, chemistry, oceanography, and engineering under a unified umbrella.
10
This has been truly enriching for me and my students, as well as my materials science, chemistry, physics, and biology colleagues and their students. In the process, I was fortunate to learn and use a lot of physics, chemistry, and create and use new experimental techniques.
The work on ionic polymer‐metal composites which are electro‐active soft actuators and sensors, would have been impossible without collaboration with my chemistry colleague, Yitzhak Tor. Similarly, my work on modeling, design, fabrication, and characterization of healable composites with negative refractive index, could not have been possible without collaboration with my son, Syrus, who was a PhD graduate of UCSD’s physics department, and with his coworkers, David Smith and others, as well as with Yitzhak.
While it was in some measure Governor Ronald Reagan’s attitude toward the University of California that helped to drive me back to Northwestern in 1970, it was also his support as the President, of university research through his URI (University Research Initiative) program that allowed me to create a large experimental laboratory at UCSD, as well as to attract ten new faculty colleagues in Mechanics and Materials within the span of only three years.
Within the same span of time, a major center with the state‐of‐the‐art and some novel facilities was created at UCSD, under the sponsorship of ARO, called the Center of Excellence for Advanced Materials (CEAM), a rather challenging name to live up to!
Here again I was very lucky in not only securing ample research funds, but also in having excellent colleagues and coworkers, such as John Starrett, who unfortunately passed away at the young age of 47 in 1990, and Jon Isaacs, who has been with me since 1987. In our laboratory we can quantify the thermo‐mechanical and electromagnetic properties of a broad class of materials, as well as fabricate multifunctional self‐healing and self‐sensing composites.
Let me finish with two comments.
To my young colleagues and students, I say follow your passions, as I have been fortunate to follow mine and actually get paid for it.
To the Timoshenko Medal Committee I give my greatest thanks for honoring me in Boston which, in the mid 1800s, was the intellectual hotbed of antislavery and pro women’s rights. It was in 1823 when Thomas Wentworth Higginson was born in the neighboring town, Cambridge, graduated from Harvard at the age of 18, and led an intellectual yet action‐oriented fight for black‐Americans and women’s equality. In 1904 Higginson anticipated that eventually
“marriage may come to be founded, not on the color of the skin, but on the common courtesies of life, and upon genuine sympathies of heart and mind.”
11
Although, he may have been 100 years ahead of his time, I have no doubt that he would have been proud to see two women striving for the highest offices in the land, and the son of a black African father and a white American mother graduating from Harvard and potentially attaining the presidency.
Thank you very much for listening to me and let us go to see if he has done it!

Committee on FluidStructure Interaction The CFSI organized two invited mini symposia: “Advances in Computational Techniques for Fluid Mechanics and Fluid‐Structure Interactions” at Coupled Problems 2009, and “Fluid‐Structure Interactions” at Marine 2009. Both conferences, which took place in June of 2009, are a part of the European Community on Computational Methods in Applied Sciences (ECCOMAS) and International Association for Computational Mechanics (IACM) Thematic Conference series. Yuri Bazilevs (UCSD) and Tayfun Tezduyar (Rice University) were the minisymposia chairs. The minisymposia enjoyed good participation and attendance from both well‐established and young researchers in the fields of computational fluid dynamics and fluid‐structure interaction.
At the IMECE 2009, the CFSI is organizing a special symposium titled "Symposium Celebrating the 60th Birthday of Yoichiro Matsumoto: Advances in Computational Fluid Mechanics and Fluid‐Structure Interactions". Professor Matsumoto (Vice President, University of Tokyo) contributed much to computational and experimental fluid mechanics, mentored many young researchers in Japan, and has been a dedicated participant in research gatherings of the ASME and the computational mechanics community. This will be another occasion to recognize his accomplishments and thank him for his contributions. The symposium, chaired by Tayfun Tezduyar (Rice University), will have six sessions and will feature a large number of leading researchers, including Thomas Hughes (UT Austin), Ryutaro Himeno (RIKEN, Japan), David Gartling (Sandia National Labs), Eugenio Onate (CIMNE, Spain), Roger Ohayon (CNAM, France), Kozo Fujii (JAXA, Japan), Chisachi Kato (University of Tokyo), Andrea Prosperetti (Johns Hopkins), Takashi Yabe (Tokyo Institute of Technology), Ahmed Sameh (Purdue) and Yoichiro Matsumoto.
The CFSI is also organizing at IMECE 2009 a two‐session symposium on "Isogeometric Methods". The main theme of the minisymposium is Isogeometric Analysis, a new
23
computational framework that is based on the computational technologies of Computer Aided Design and Computer Graphics. The method was pioneered by Thomas Hughes (UT Austin), Austin Cottrell (Citi Group), and Yuri Bazilevs (UCSD) in ’05. Despite the relatively young age of this new computational technology, isogeometric analysis has evolved into a research field and has been attracting an increasing group of researchers worldwide. The Isogeometric Methods symposium is chaired by Yuri Bazilevs (UCSD) and David Benson (UCSD).

Fracture and Failure Committee The Committee held its yearly meeting at the 2008 IMECE meeting in Boston, MA. The committee leadership has traditionally rotated biennially at the summer AMD meeting. The leadership changes have been re‐aligned to occur during IMECE meetings. Therefore at the start of the 2009 IMECE meeting in Orlando, Ashraf Bastawros (Iowa State University) will become Chair and L. Roy Xu (Vanderbilt University) will become Vice‐Chair. A new Secretary will be elected and immediately pressed into service. Nominations for the Secretary position will be solicited at the start of the committee meeting. As always, committee membership is open to anyone; membership is granted by attending a committee meeting at an IMECE meeting or by contacting a committee officer.
At the 2008 IMECE meeting, the FFMTC organized a symposium to honor Professor J. Hutchinson as he moved to semi‐retirement. Professors P. Geubelle, H. Bruck, Z. Suo, T. Nakamura, A. Bastawros, and M. Walter had put out a call for papers in February of 2008 and in a relatively short time, 50 high quality papers were submitted. This resulted in a 10 session symposium! The sessions were all well attended, with many having standing room only. Harvard University sponsored a reception at the conclusion of the first day of this 4 day symposium. The food for the reception was outstanding and everyone enjoyed the short speaking program. The organizers would like to thank all who participated in the symposium and, of course, Harvard University for their generosity in sponsoring the reception.
The Committee briefly discussed further “honoree symposia” for upcoming IMECE meetings. While the honoree symposium model looks to be a successful way to organize future symposia, it is believed that the location of the meeting plays a key role in the success of such large‐scale symposia. In addition it was felt that it is too difficult to organize honoree symposia on a yearly basis. As always, discussion of symposia ideas for the 2010 IMECE will take place at the Committee’s meeting at the upcoming IMECE in Orlando. If you wish to organize a symposium Please come to our Committee meeting or talk to a committee officer.

Materials Processing and Manufacturing Committee The AMD‐MPM committee held its regularly scheduled meeting on November 3, 2008 during the IMECE 2008 in Boston, Massachusetts with S Ghosh (Chair) and X. Wu (Vice Chair) conducting the meeting. An AMD‐MPM sponsored mini‐symposium, held in IMECE 2008, is: “Processing of Micro‐ and Nano‐structured Materials” organized by H. A. Bruck and M. V. Hosur. For IMECE 2009, a mini‐symposium entitled “Plasticity and Formability of Advanced Materials” has been proposed by X. Wu, C. L. Chow and D‐J. Zhou.
There has been some concern about the recent lack of participation in the MPM committee. Given the overlap of interests in MPM with other committees in AMD and MD, the committee is looking into possible liaisons with other committees. One consideration is forming a Joint Committee on Materials Processing with the Materials Processing committee in MD. The next MPM Chair is X. Wu and the Vice Chair is H. Cherukuri.
