This paper aims to investigate the fine-blanking process by using the finite element method. To avoid the divergence tendency in the computation, remeshing and tracing method as well as the golden section method were developed and introduced into the finite element program. Through simulation, the mesh distortion and the distributions of the stress and the strain were obtained. Furthermore, a large strain analysis technique was employed to determine the effective strain distribution based on the experiment. The effective strain distributions from the simulation were in accordance with the experimental ones. Besides, the varying tendency of the simulated effective strain was similar to that of the hardness value measured from experiment, reflecting that the hardened material layer on the blanked edge was just the result from the severe deformation in the blanking operation.
