Abstract:

It has long been found that the crystal orientations would induce macroscopic anisotropy during deformation process, and then affect the deformation properties of sheet metal. So it is very important to find the true relation between texture distribution and macroscopic anisotropy. In this paper, the anisotropy coefficients of the yield function are fitted by Taylor factor and crystal plastic model. Metal flow is assumed to occur by crystallographic slip on given slip systems within each crystal. Then this simulation results are compared with those of microscopic crystal plastic method.
