2.2.1.6 Defining Material Properties
Most element types require material properties. Depending on the appli-
cation, material properties can be linear (see Linear Material Properties)
or nonlinear (see Nonlinear Material Properties). As with element types
and real constants, each set of material properties has a material reference
number. The table of material reference numbers versus material property
sets is called the material table. Within one analysis, you may have mul-
tiple material property sets (to correspond with multiple materials used in
the model). ANSYS identifies each set with a unique reference number.
While defining the elements, you point to the appropriate material refer-
ence number using the MAT command.
2.2.1.7 linear Material Properties
Linear material properties can be constant or temperature-dependent,
and isotropic or orthotropic. To define constant material properties
