One of the new research fields in plasticity is related to choosing a proper non-associated flow rule (NAFR), instead of the associated one (AFR), to predict the experimental results more accurately. The idea of the current research is derived from combining von Mises and Tresca criteria in the places of yield and plastic potential surfaces in rate-independent plasticity.  This idea is implemen...

Abstract In this contribution, a model for the thermomechanically coupled behaviour of case hardening steel is introduced with application to 16MnCr5 (1.7131). The based on decomposition free energy into thermo-elastic and plastic part. Associated viscoplasticity, in terms temperature-depenent Perzyna-type power law, combination an isotropic von Mises yield function takes respect strain-rate de...
