摘要：

Finite element analysis has been performed to investigate the effect of V-ring indenter on the sheared surface in the fine blanking of pawl, which is a part of the automotive safety belt and is made of AISI1045 sheet. The Cockcroft and Latham's fracture criterion and the element kill method are used in order to simulate the blanking operation successfully. Simulation results are obtained for various positions and heights of the V-ring indenter, and the experimental results are compared with theoretical results. It is shown that the FEM simulation results can be useful for predicting the optimal condition for fine blanking products. (C) 2003 Elsevier Science B.V. All rights reserved.
