Three-dimensional FEM analysis for rolling processes is developed. It is based on finite deformation theory using co-rotational formulation. Three-dimensional FEM analyses of cold rolling processes are requested to predict 'shape' or flatness of rolled sheet, then the precise three-dimensional analyses of residual stresses are needed. Present report describes the method we used for developing an elastic-plastic code for analyzing such rolling processes, and several results of simulations are shown and discussed.
