Abstract

Results of a comprehensive study on deep drawing are presented. The numerical results are based on finite element procedure developed for simulation of arbitrarily shaped, 3-D forming operations. The elastic-plastic material description with Hill’s anisotropic model is employed allowing for elastic effects, unloading, and multistage processes. By applying a proper computational model of large strain and large rotation plasticity, reliable results were obtained even using relatively simple material and friction laws. Predicted values of the press force, strain distributions, and flange reduction are compared with the corresponding results from axisymmetric deep draw experiments for a wide range of materials used in real forming applications including a deep drawing quality steel, brass, high strength steel, stainless steel, and aluminum. The parametric study shows the sensitivity of the solution on material parameter variations. Presented results can be considered as a set of benchmark problems.
