Abstract In order to explore the mechanism and influencing factors of the periodic thickness fluctuation at the composite interface after rolling,a finite element model of aluminum/steel/aluminum three-layer symmetrical composite plate rolling was established based on commercial FEM software ABAQUS. Through the analysis of the stress variation law of each layer in the rolling process of the clad plate,it is found that the deformation of steel layer and aluminum layer is obviously inconsistent,and the deformation trend of the aluminum layer is obviously greater than that of the steel layer,which leads to the tensile stress in the rolling direction of steel layer and the thickness thinning of steel layer. At the same time,the occurrence of thickness thinning changes the stress distribution in the surrounding area and makes the thickness fluctuation presents periodic characteristics. The correctness of the simulation and analysis results is verified by the rolling experiment in the laboratory.

Key words： clad plate rolling periodic fluctuation of interface thickness thinning model
