Specifying cycled yield stress data for the ORNL model

You can use the Suboption editor to specify the tenth-cycle yield stress and hardening values for the ORNL constitutive model. This option is relevant only if you also follow the procedure described in Using the Oak Ridge National Laboratory (ORNL) constitutive model in plasticity and creep calculations.”

  1. Create a material model as described in Using a linear kinematic cyclic hardening model to define classical metal plasticity.”

  2. From the Suboptions menu in the Edit Material dialog box, select Cycled Plastic.

    A Suboption Editor appears.

  3. Toggle on Use temperature-dependent data to define data that depend on temperature.

    A column labeled Temp appears in the Data table.

  4. In the Data table, enter values for the yield stress, plastic strain, and, if applicable, temperature.

    For detailed information on how to enter data, see Entering tabular data.

  5. Click OK to return to the Edit Material dialog box.
