  • A bimetallic composite rolling deformation partitioning model was established based on the finite element simulation of roll deformation process of copper clad aluminum bimetallic composites. The deformation zone was divided into five parts, namely, elastic region, single material plastic zone, back slip zone, knead rolling area and forward slip zone. On the basis of theoretical calculation formula of rolling load for single material, the rolling load calculation formula for bimetallic composites was proposed by simulating the rolling process of copper clad aluminum composites with variables of different Cu volume fractions. The rolling load formula was verified by rolling test and the finite element simulation of rolling process for copper clad aluminum composites with different reduction rates.
