Specifying user subroutine UHARD to define classical metal plasticity

User subroutine UHARD allows you to define the yield surface size and hardening parameters for isotropic plasticity or combined hardening models.

  1. From the menu bar in the Edit Material dialog box, select MechanicalPlasticityPlastic.

    (For information on displaying the Edit Material dialog box, see Creating or editing a material.)

  2. Click the arrow to the right of the Hardening field, and select User.

  3. In the Data table, enter the number of Hardening Properties needed as data in user subroutine UHARD.

  4. Click OK to create the material and to close the Edit Material dialog box. Alternatively, you can select another material behavior to define from the menus in the Edit Material dialog box (see Browsing and modifying material behaviors, for more information).
