The theoretical and numerical framework for the simulation of impacts on thick sandwich composite plates is presented. It encompasses three new elements: 1) A three-dimensional layerwise theory, which approximates the in-plane and transverse displace

A general elastoplastic contact/impact model of a spherical object and a supported transversely isotropic composite layer or a half-space is presented. The main feature of the model is a contact law that is developed based on elastic–plastic and fu
