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