A material data table is a series of constants that are interpreted when they are used. Data tables are always associated with a material number and are most often used to define nonlinear material data (therefore requiring an iterative-solution analysis). Examples of nonlinear material data include stress-strain curves, creep constants, swelling constants, and magnetization curves. The material data table is defined via the TB command.
For some element types, the data table is used for special element input data other than material properties. The form of the data table depends upon the data being defined:
Where the form is peculiar to only one element type, the table is described with the element in Element Library.
If the form applies to more than one element, it is described here and referenced in the element description.
