Distortional Hardening Rules for Metal Plasticity


A brief overview of the available experimental data regarding distortional hardening of metals is first presented. This material is subsequently used to motivate the need for accurate distortional hardening rules in computation. A general expression for the yield surface of a plastic material is proposed that includes the isotropic‐kinematic von Mises model as a particular case and that can be systematically used to incorporate distortional hardening features into the material modeling in a simple manner. This expression is complemented with suitable rate equations for the parameters involved. The proposed model is particularly convenient for computer implementation.
