The Simulation of Shear Angle and Deformations of Cu/Al Composite Sheets during Accumulated Roll Bonding

摘要

The present simulation study gives shear angle distribution and deformations, there in the effect of severe plastic deformation due to the accumulated roll bonding on the crystalline structure of materials is discussed. In the simulation, the classical metal plasticity models with a von Mises yield surface and the PLASTIC, HARDENING = ISOTROPIC as keyword in ABAQUS, were employed. The equivalent strain, ε_(eq), imposed by rolling is defined as micro-hardness was used to characterize the mechanical properties. After four cycles, the mechanical properties were improved with increasing ARB cycles.
