Modification of Hardening Parameter for Computational Plasticity

15973

Hardening can be defined as increase in the strength of a material due to plastic deformation. A type of hardening, which is work hardening, is performed under the cold working conditions. In metallic solids permanent change of shape is generally carried out on a microscopic scale by defects called dislocations which are created by stress. In addition, Hardening parameter is so critic for the computational plasticity. In this study, the hardening parameter, which has emerged from the variation of yield surface equation, has been considered. It has been isolated from hardening rule and investigated that the parameter must have a unique value for any hardening rule.
