Three-Dimensional Deformation Process Simulation with Explicit Use ofPolycrystalline Plasticity Models

摘要

The combination of massive parallel processing and polycrystalline plasticitytheory offers the potential for applying detailed microstructural models to macroscopic deformation processes. In the work the finite element method is used to solve for the three-dimensional deformation of a plastic workpiece. The interaction of the material symmetry adopted in analysis of pole figures and the boundary conditions posed in the plasticity boundary value problem are 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.
