8.4.2.3. RATE and CHAB and PLAS (Multilinear Isotropic Hardening) Example.
In addition to the TB,MISO example (above), you can also use material plasticity, the multilinear isotropic
hardening option - TB,PLAS, , , ,MISO to combine viscoplasticity and Chaboche nonlinear kinematic
hardening plasticity. An example of the combination is as follows:
