This paper presents an analytical method to solve the dynamic crushing force and collapse characteristics of rotational ellipsoidal composite-reinforced metal shells with foam filler. The collapse model is firstly simulated by means of finite element calculation. Then, the feasibility of the analytical method is proved by a comparison with the finite element simulate. In example calculations, effects of some key parameters on the dynamic crushing force of rotational ellipsoidal composite-reinforced metal shells with foam filler are described and discussed. Results obtained can be used as a valuable reference for the design of protective structures resisting impact loads.
