Engineering Data supports the following general classes of isotropic hardening:
In addition to the above topics, the Rate-Independent Plasticity section of the Mechanical APDL Material Reference includes detailed theoretical and background information on isotropic hardening.
Important: In release 2022R2 (or prior), the application defined the Bilinear Isotropic Hardening and Bilinear Kinematic Hardening material models using . When you open a project from these previous releases, the Active Table property for the material models displays the value . For this scenario, if the temperature is constant, or the same (tabular) temperature values are used for Isotropic Elasticity and the hardening model data, the application provides the right-click option for the Active Table value cell. See the Bilinear Isotropic Hardening topic in the Rate-Independent Plasticity section of the Mechanical APDL Material Reference for more information about the conversion.
