Abstract：

The bending process of composite plate was simulated by finite element simulation software ABAQUS. Then, the bending properties of stainless steel/aluminum alloy/stainless steel laminar metal composite plate and single-layer metal plate were compared and analyzed, and the interfacial delamination damage was studied by using a bilinear cohesion force model. The results show that the bending properties of stainless steel/aluminum alloy/stainless steel laminar metal composite plate are complex, the stress of each layer for metal plate is different during bending, and the stress is mainly concentrated in the center of bending. The 430 stainless steel plate withstands the greatest stress, followed by the 304 stainless steel plate, and the smallest is the 3003 aluminum alloy plate. The study of delamination damage finds that the delamination damage occurs between every two layers of metal plate, and the delamination damage between the 304 stainless steel plate and the 3003 aluminum alloy plate is more serious than that between the 430 stainless steel plate and the 3003 aluminum alloy plate. In addition, the reliability of the simulation results is verified by experiments.
