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).
