The destruction aspect of the materials appears differently depending on the behavior of load acting on the materials. Otherwise, the behavior of materials on the static load is different from the behavior of materials on the impact load. In this study, the variation in maximum shearing stress of copper shear pin depending on the shearing rate is researched. The input velocity of shear load goes increase, but the initial and last shearing rate are constant within a cycle of all. The pre-analysis has been proceeded using the method of explicit dynamic analysis which are Ansys and Autodyn. And then, the experimental shearing performance research has proceeded to confirm these phenomena.
