Effect of Kinematic Hardening on the Initiation and Growth of Shear Bands in Plane Strain Deformations of a Thermoviscoplastic Solid
Abstract
We study dynamic thermomechanical deformations of an elasto-viscoplastic body deformed in plane strain compression at a nominal strain-rate of 5 000 sec-1. The boundaries of the block are assumed to be perfectly insulated. We model the thermoviscoplastic response of the material by the Brown-Kim-Anand constitutive relation in which the evolution of the microstructural changes is accounted for by two internal variables, viz. a scalar and a traceless symmetric second order tensor. The former accounts for the isotropic hardening of the material, and the latter for the kinematic hardening. We model a material defect by introducing a temperature perturbation in the stress-free reference configuration. It is found that the consideration of kinematic hardening does not change the qualitative nature of results. © 1994 Springer-Verlag.
