LS-DYNA VALIDATION AND VERIFICATION

1 INTRODUCTION

This report provides the quality assurance documentation for validation and verification of the LS-DYNA explicit finite element program in accordance with TNW Quality Assurance Procedures Manual (Ref. 1). The LS-DYNA version that is being V&V is Version 950c (07/12/99), procured from Livermore Software Technology Corporation (LSTC). The hardware platform on which it is installed at TNW consists of an Intel PIH600 PC, and Windows NT 4.0, Build 1381, service pack 5 opeating system. LS-DYNA was installed in this platform on 12/20/99. The applicable User's Manual is LS-DYNA Keyword User's Manual, Version 950 (Ref 2).

2 V&V TEST PLAN AND ACCEPTANCE CRITERIA

The LS-DYNA V&V plan implemented in this report consists of three parts as follows:

1. Part 1 Test Problems: These test problems serve to verify that the installation of LS-DYNA on the TNW platform has been performed correctly and produces essentially identical results as those run in LSTC system. For this purpose, ten sample problems, provided by LSTC, are executed and results verified against the results provided by LSTC.

Acceptance Criteria: LS-DYNA results on the TNW platform shall be within 1% of the results provided by LSTC.

2. Part 2 Test Problems: These test problems are intended to verify LS-DYNA against a public domain finite element code such as ANSYS. A set of five sample problems used for the V&V of the ANSYS program are selected. These sample problems are based on close form solutions available in standard engineering textbooks. The ANSYS results are compared with results produced by LSDYNA.

Acceptance Criteria: LS-DYNA results shall be within 10% of the ANSYS/close form solution results. The basis for this criterion is the differences in modeling and numerical solution algorithms between LS-DYNA (explicit) and ANSYS (implicit).

3. Part 3 Test Problems: These test problems consist of a set of sample problems executed to specifically demonstrate proper execution of the sliding and contact solution algorithms in LS-DYNA. The LS-DYNA responses are verified against first principles of rigid body dynamics, solutions available in the open literature,

and/or solutions obtained by comparison with another finite element code (SAP2000).

Acceptance Criteria: The same acceptance criterion is used as for Part 2 Test Problems.

4 CONCLUSIONS

It is concluded that LS-DYNA has been properly installed at TNW computer and that it has been validated and verified for use.

Note: Results documented in References 5 and 6 (both Rev. A since design data is preliminary) were used for comparison with LS-DYNA results for purposes of LSDYNA V&V. Dynamic properties of the AHSM (e.g. mass, cg location, mass moment of inertia, etc.) consistent with those in References 5 and 6 were used in the LS-DYNA analyses. Any future revisions to these calculations as a result of final design of the AHSM do not relate to the purpose not affect the conclusions of this V&V report.
