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 components. The texture evolution has a strong influence on the residual microstresses and produces non-linear d vs. sin(2) psi-curves. The texture evolution 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. Examples are given for the inverse pole figure and non-linear d vs. sin(2) psi-distributions due to cold torsion of an austenitic steel. (C) 1999 Elsevier Science B.V. All rights reserved.
