A hit by a falling of a metal box is a canonical contact problem. This article uses ABAQUS software to analyze the collisional procedure about the dropping of a metal box in four types of ground contact as triangular bulge, semicircle arc bulge, rectangular bulge and plane, and then compare different mechanical behaviors of the contact-material in different types of contact, which bores out the symmetry of symmetrical structures loaded symmetrically in Structural Mechanics. Besides, it has
