  1. Considering Hardening in Orthotropic Plastic Analysis

    Considering Hardening in Orthotropic Plastic Analysis

    In RFEM, orthotropic plastic analyses using the plasticity criterion Tsai‑Wu have been possible for quite some time now. With the recently implemented hardening module k, you can also take into account the hardening of the material in the iterative calculation.

    Using Tsai-Wu Material Model (Orthotropic Plastic)

    With the orthotropic plastic material model in RFEM 5, you can calculate solids with plastic material properties and evaluate them according to the so‑called Tsai‑Wu failure criterion. The Tsai‑Wu criterion goes back to Stephen W. Tsai and Edward M. Wu who published it in 1971 for plane stress states.
