Simulation of the development of deformation textures and residual stresses using the Taylor-Bishop-Hill theory

Cold working processes due to inhomogeneous and strong plastic deformations result in the formation of residual stresses and texture within the compon ents. The texture evolution has a strong influence on the residual microstr esses and produces non-linear d vs. sin(2) psi-curves. The texture evolutio n and the resulting non-linear d vs. sin(2) psi-curves are calculated here using the Taylor-Bishop-Hill theory and an elastic unloading model. Example s are given for the inverse pole figure and non-linear d vs. sin(2) psi-dis tributions due to cold torsion of an austenitic steel. (C) 1999 Elsevier Sc ience B.V. All rights reserved.
