Bi-linear isotropic hardening not working in ANSYS Workbench 2023?

  Trying to create a material with bilinear isotropic hardening. Material has plastic behavior (see row 11 in attached). This was not in previous versions and I cannot set both elastic and plastic portions. Help?

  Hello John,
  You don't need to specify both elastic and plastic properties under the Bilinear Isotropic Hardening. The entry "Active Table" is ready-only and is re-named to "Tangent Modulus Type" since 2024R2. Using the Bilinear Isotropic Hardening model, you only need to provide the initial yield stress and the slope of the stress-plastic strain curve. Elastic properties are defined earlier under Isotropic Elasticity (row 4 in your screenshot).
