Abstract：

An elastic-plastic finite element model of asynchronous rolling for Cu/Al/Cu clad sheet was established by software ANSYS/LS-DYNA, and the accuracy of the finite element model was proved by comparing the simulation results of finite element model with the actual rolling experiment results. Then, through the analysis and study of asynchronous rolling deformation zone, it is found that under the same conditions, compared with synchronous rolling, the asynchronous rolling effectively reduces the rolling normal stress and increases the friction stress in the backward slip zone, and the cross-shear zone of asynchronous rolling promotes the metal flow at the bonding interface of clad sheet. Under the same conditions of other rolling, the larger the reduction rate is, the smaller the cross-shear zone is, the larger the asynchronous speed ratio is, and the larger the cross-shear zone is. The equivalent strain of the bonding interface copper sheet near the fast roll side is greater than that near the slow roll side, and the equivalent strain of the intermediate aluminum sheet is greater than that of copper sheets on both sides. With the increasing of asynchronous speed ratio, the equivalent strain difference between the two metals on the bonding interface of the clad sheet is gradually reduced, and the deformation becomes more coordinated, which is conducive to enhancing the bonding strength of the clad sheet. The research provides theoretical basis for the preparation process optimization of copper-aluminum clad sheet.
