***behavior#

Description#

This command is more fully described in the chapter Material Models and Material Components. This command lets the user include in-line a material definition in the Z-mat interface file. If this command is not used, the material file will be sought using the *file or *standard sub-commands of ***material.

Be aware of the following items when defining a Z-mat behavior.

  • Behavior definitions have the “external parameter” value temperature available always for coefficient definitions, thermal strains, and similar coefficient taking material objects. With ABAQUS, additional field variables can be defined using the field options.

    • 1from version 5.6 handbook

  • One may use the Lagrangian modifiers to transform the behavior into finite strain when the conditions for calculating the deformation gradient in a UMAT have been met (see ABAQUS user manual 25.2.26 1from version 5.6 handbook).

  • For use with ABAQUS/Explicit one must add the material modifier explicit.
