Abstract: A method to simulate the rolling process of bimetal composite sheets was given. Based on rigid-plastic finite element method，in terms of experiment results， and by the means of FEM software ANSYS，the deformations， stresses，strains，plastic flowing in sheets, rolling forces and rolling moments in symmetrical or asymmetrical rolling of bimetal composite sheets were analyzed. The results above were expressed in computer animated way. An effective approach to predict rolling results and to reduce test time and test cost is provided.
Key words: rolling of bimetal composite sheets; numerical simulation; rigid-plastic finite element method
