The procedure to specify anisotropic elastic material properties resembles that for nonlinear properties.
You first activate a data table using the TB command (with Lab = ANEL) and then define the terms of
the elastic coefficient matrix using the TBDATA command. Be sure to verify your input with the TBLIST
command. See Data Tables - Implicit Analysis in the Material Reference manual and the appropriate element
descriptions for more information.
1.1.4.4. Material Model Interface
The program includes an intuitive hierarchical tree structure interface for defining material models. A
logical top-down arrangement of material categories guides you in defining the appropriate model for
your analysis.
1.1.4.4.1. Accessing the Interface
You access the material model interface from Main Menu> Preprocessor> Material Props> Material
Models. The Define Material Model Behavior dialog box appears, which originally displays the top
level of the tree structure, as shown in Figure 1.3: Material Model Interface Initial Screen (p. 8).

1.1.4.4.2. Choosing Material Behavior
The Material Models Available window on the right displays a list of material categories (for example,
Favorites, Structural, Thermal, Electromagnetics).
NoteIf you select an ANSYS LS-DYNA element type, only one category named LS-DYNA appears.If a category is preceded by a folder icon, there are subcategories available under the main category.
When you double-click on the category, the subcategories appear indented, and below the category
as shown in Figure 1.4: Material Model Interface Tr ee Structure (p. 9).
