Abstract
Numerical analysis is carried out in order to investigate the influence of plastic anisotropy on sheet metal forming processes such as stretching and deep-drawing. The analysis is based on the deformation theory and Hill’s theory of plastic anisotropy. The numerical results are compared to experiments. It is shown that the neglect of the anisotropy in the simulations leads to inaccurate results. Using the yield stresses and anisotropic parameters from tensile and bulge tests, the earing in deep-drawing of a circular blank is calculated correctly.
