Three-Dimensional Deformation Process Simulation with Explicit Use of Polycrystalline Plasticity Models.

Abstract

The combination of massive parallel processing and polycrystalline plasticity theory offers the potential for applying detailed microstructural models to macroscopic deformation processes. In this work the finite element method is used to solve for the three-dimensional deformation of a plastic workpiece. The interaction of the material symmetry pole adopted in analysis of pole figures and the boundary conditions posed in the plasticity boundary value problem is examined. It is shown that the use of spatially distinct aggregates in a material experiencing local kinematic inhomogeneities throughout its deformation history leads to texture predictions which compare favorably with experimental measurements.
