/MAT/LAW25 (COMPSH)

Two variations of the same material law type 25 are implemented: Tsai-Wu formulation and CRASURV formulation.

• If the formulation flag I_form (Line 2, field 7) is set to 0, the plasticity model is based on standard (Tsai-Wu) formulation is used. Refer to the /MAT/LAW25 (Tsai-Wu Formulation (Iform =0)) keyword.
• If the formulation flag I_form (Line 2, field 7) is set to 1, the plasticity model is based on CRASURV formulation is used. Refer to the /MAT/LAW25 (CRASURV Formulation (Iform= 1)) keyword.
