摘要：The simulation method for ARB(accumulative roll bonding) and the constitutive model of the ARB specimen were studied. Based on the ZA(Zerilli-Armstrong) model, with MSG(mechanism-based strain gradient) theory and Hall-petch principle, considering its temperature, strain ratio and the effect of the texture variation to the mechanical property, its dynamic constitutive model was established, and verified through the experiment. Moreover, the finite element simulation method for ARB process based on the dynamic constitutive model established was proposed and verified through the experiment. The study in the paper provides analysis method and theory foundation for ARB.
