The Influence of Non-Dissipative Quantities in Kinematic Hardening Plasticity
(2002) In Key Engineering Materials 233-236(ii). p.773-778- Abstract
- A kinematic hardening plasticity model valid for finite strains is presented. The model is based on the well-known multiplicative split of the deformation gradient into an elastic and a plastic part. The basic ingredient in the formulation is the introduction of locally defined configurations - center configurations- which are associated with deformation gradients that are used to characterize the kinematic hardening behavior. One of the aspects of the model investigated here is found when the plastic and kinematic hardening evolution laws are split into two parts: a dissipative part, which is restricted by the dissipation inequality, and a non-dissipative part, which can be chosen without any thermodynamical considerations.

To investigate the predictive capabilities of the proposed formulation, the simple shear problem and torsion of a thin-walled cylinder are considered. In the numerical examples it turns out that the non-dissipative quantities affect the response to a large extent and are consequently valuable ingredients in the formulation when representing real material behavior.
