To design the layout of tools, it is important that the influence of shearing conditions on the accuracy of the blanked product should be considered. In this paper, we discuss the influence of constraint of a material on shearing phenomena, especially punch bending, through an experiment and elastic-plastic finite element method. The results of this study clarified the following. The constraint of the material influences on the shearing phenomena such as punch bending, material flow, shearing forces and so on. When one side of a material is constrained, the direction of punch deformation is opposite to the side of material constraint. The material constraint influences on the lateral displacement of the punch tip consists of a bending components by horizontal force.
