AN ANALYSIS OF LOW-VELOCITY IMPACT OF SPHERES ON ELASTIC CURVED-SHELL STRUCTURES

A solution method for dynamic analysis of low-velocity impact between elastic curved-shell structures and spheres is presented. The discretized nonlinear impact equations are derived based on the degenerated shell FE formulation and the Hertzian contact theory. They are numerically integrated to get various transient responses such as contact force and other field quantities. The validity and applicability of the method are shown numerically with two model problems of practical importance.
