Abstract

A thin interphase between two different elastic media is under consideration. It is assumed that the intermediate layer consists of a soft elasto-plastic material whose Young's modulus is small enough in comparison with those of the bounding materials. Using an asymptotic technique, nonlinear transmission conditions for the bimaterial structure are evaluated. As a numerical example, a FEM analysis of a bimaterial structure with an interface is performed to investigate the accuracy of the derived transmission conditions.
