In order to describe nonproportional cyclic plasticity of polycrystalline metallic materials, the hardening function is separated into three factors, in which,f1 is related to the hardening parameter determined by plastic strain range, and f2 and f3 are related to the change of plastic deformation path characterized by a measure of nonproportionality. The main features of this work are: (a)cyclic hardening is described by f1, and additional hardening is separated into instantaneous and hereditary one which is described by f2 and f3 respectively; (b)a general form of the evolution of f1(i= 1,2, 3) is proposed; (c)parameters a1 and a3 are introduced to keep the memory to the largest cyclic hardening and additional hardening respectively; (d)various hardening mechanisms are embedded into a thermomechanically consistent constitutive equation. The capability of the developed model is verified with the analysis of biaxially nonproportional experiments by Benallal et al, Tanaka et al and Ohashi et al.

The hardening function of the Tresca yielding criterion under isotropic hardening has been rarely discussed in literatures. A hardening function is put forward in this paper. It can match with the Tresca yielding criterion with comparatively sufficient experimental evidence. Then the increment stress- strain relation of plasticity on the corner of the yielding surface is presented by the Koiter theory which is connected with the above hardening function.

The total stress response of material is decomposed into a sum of an equilibrium stress response and a non-equilibrium overstress response. Correspondingly, a rate independent intrinsic time and a rate dependent intrinsic time are defined respectively. Additional hardening functions to describe the isotropic and anisotropic nonproportional effects are assumed to relate to the accumulation of plastic strain component along the normal of eqilibrium stress trajectory, in which the effects of geometry of the loading path are included. An endochronic constitutive model for rate dependent, nonproportional cyclic plasticity is formulated and is applied to simulate the stress responses of stainless steel XCrNi18 9 for some typical loading programs at different loading rates. The predictions are compared with the experimental results by Haupt and Lion, showing good agreement and demonstrating the capability of the model.
