Analysis of Plastic Behavior to Cyclically Uniaxial Tests Using an Endochronic Approach

Abstract

This paper is devoted to the modeling of metallic materials behaving path dependent strain/loading hardening using endochronic theory. Characteristics of the model include the description of the strain path dependent rate of kinematic hardening and of the strain path dependent distortion of the yield surface. Comparisons between theoretical and experimental results are presented to proof the theory. It is shown that the present model can reasonably predict stress response to uniaxially cyclic loading under a variety of test conditions. In particular, the celebrated Bauschinger effect, which is well-known to be inadequately described by the classical plasticity theories, can be quantitatively predicted well by the model.
