Constitutive Model of Large-Strain Cyclic Plasticity for Orthotropically Anisotropic Materials

YOSHIDA Fusahito, UEMORI Takeshi

Proceedings of the ... annual meeting of JSME/MMD 2002 131 - 132 2002.10

Language：Japanese Publisher：The Japan Society of Mechanical Engineers

This paper presents a framework of constitutive modeling of large-strain cyclic plasticity which describes both the deformation-and texture-induced anisotropies of materials. In this model, the transient Bauschinger effect is described accurately by a new equation of the backstress evolution, and the strain-range and mean-strain dependencies of cyclic strain-hardening are expressed by a model of workhardening stagnation. For the description of texture-induced anisotropy, any of widely accepted yield criteria of orthotropic anisotropy is easily incorporated into this model.

Elastic-Plastic FEM Analysis of Springback in Sheet Metal Forming

Language：Japanese Publisher：Yuge National College of Maritime Technology

This paper shows how the prediction of springback is influenced by the description of the Bauschinger effect in constitutive models. Constitutive models describing both the texture-induced anisotropy and the Bauschinger effect were derived on the basis of Hill's quadratic yield function and some kinematic hardening rules. Springback in V-bending was simulated by using the developed elastic-plastic finite element code incorporating three different types of constitutive models : (A) an isotropic hardening model, (B) a model of combined linearly kinematic hardning and isotropic hardening, (C) a model of combined linearly and non-linearly kinematic hardening and isotropic hardening. From the simulated results, it is concluded that the Bauschinger effect must be taken into account for the accurate prediction of the springback.
