The corrugated rolling is a new rolling technology to obtain the composite plate. Compared with the flat rolling, the corrugated rolling can promote the plastic deformation of hard metal effectively and gain a composite plate with superior mechanical properties. In this paper, the finite element analysis of the copper/aluminum composite plate in corrugated rolling process was carried out. The correctness of the model was verified by experiment. The distributions of rolling normal stress, shear stress, equivalent strain and cross shear zone in corrugated rolling were obtained, and the differences between these from flat rolling were contrasted. Cross shear zone and shear stress in corrugated rolling are larger than flat rolling, which is beneficial to metal composite.
