A three dimensional finite element code with a polycrystal plasticity model is used to predict the development of surface roughness during underlying bulk deformation. Surface roughness is an important issue for many metalforming industries, especially automobile and beverage can companies. The orientation of individual grains in the material results in anisotropic behavior, and the surface grains, due to their individual orientations, do not deform uniformly. As a result, a roughening of the surface occurs. To model this development, a polycrystal finite element model will be used. The code, specifically developed for running on the CM-5 machine, takes advantage of the parallel processing environment to perform element and grain level computations in parallel. Numerous simulations will be performed to investigate the effect of various process parameters on the development of surface roughness and a concurrent experimental program will provide data for validation of the numerical simulations.
