摘　　要：本文用DEFORM-2D软件对AISI-1035钢的落料往复精冲工艺进行了弹塑性大变形有限元数值模拟,获得了材料变形过程中的材料流动速度场、应力场、应变场、等效应力和等效应变的分布,并对精冲最后阶段裂纹产生、发展和最终断裂的过程进行了分析。Numerical simulation of the reciprocated fine blanking process for AISI-1035 steel which contains large deformation in elastic plasticity has been conducted with the software DEFORM-2D.The distribution of developing trend of the material flow, equivalent stress, and equivalent strain in the course of deformation of the material has been gained.The emergence, development and final fracture of the fine cracks in the final fine blanking process have been predicted.
