Training ManualEngineering Data
The Engineering Data application provides overall control for material
properties.
Engineering data is a part of every project.
Engineering data can be opened stand alone (as a precursor to starting
a project for example).
To edit the EngineeringData in an existing
project RMB > Edit or
double click
To open the Engineering Datastandalone, add from the
component systems in the toolbox
(drag/drop or double click), then
RMB > Edit or double click.

A list of available material
libraries is displayed. These may
be ANSYS supplied or user
defined.
The Engineering Data field represents thelist of materials which have been imported
for use in the current project
Favorites are materials which will be
available in every project without the need
to import from a library.
Check box allows
library to be unlocked
for editing.
Browse for existing
libraries or choose
new library location.

Training Manual. . . Engineering Data
The toolbox provides numerous material property definitions that can beadded to existing or new materials.
To modify materials in existing libraries the library must be unlocked,(note this permanently modifies the material stored in that library).
Materials in the current projects engineering data can be modified withoutaffecting the material library.
The Toolbox Customization settings
allows filtering of the properties
displayed in the toolbox.

To add a material from an existing library to
the current project click the plus sign (+)
next to that material (or drag and drop thematerial to Engineering Data)
Any material defined in the current project
will be marked as show at right.
Once added each material becomes
available for use in the current project (it
becomes part of the current Engineering
Data).
Note, to add a
material to the
Favorites list,
RMB the material
and add.

To add a new material, first select where you wantthe material data to be stored
Note, materials need not be stored in a library butcan be added to the current project by storing inEngineering Data.
Next provide a name for the material and beginadding components and properties from theToolbox.

Training ManualMaterial Models for Explicit Dynamics
Material modelcomponents are brokeninto categories
User can choosecomponents from eachcategory, as required
If a selected component
is dependant on physicalparameters, they will alsobe selected automatically
If a selected componentprecludes componentsselected earlier, thosecomponents will be
automatically suppressed
If you want themremoved, you must dothis manually

Training ManualLibraries for Explicit Dynamics
Engineering Data provides
two libraries containing data
suitable for Explicit Dynamics
Explicit Materials
Contains a wide range of
materials generally used in
non-linear explicit analyses
Models cannot be used for
implicit analyses (e.g. pre-
stressing)
General Non-linear Materials
Contains basic material data
for non-linear analysis.
Common engineering
materials
Suitable for use in implicit and
explicit analyses
