This research had as its primary objective the development of rigorous physical descriptions and corresponding numerical strategies for the treatment of dynamically contacting solid and structural entities, and produced useful new algorithms for de script ion of dynamic frictional response, coupled thermomechanical interfacial behaviors, elastic and inelastic impact interaction, and tribological complexity. The unifying goal of this work was to assure that problems involving transient impacts between solids could be numerically solved with the same level of robustness, accuracy, and physical insight as is currently brought to bear in other areas of nonlinear mechanics. The results obtained in this work have importance well beyond contact mechanics, extending also to other applications where computational models of neighboring, but distinct, domains must be coupled together in a numerically accurate manner.
