Abstract:

This investigation explores the characteristics of deformation at the interface of dissimilar materials such as concrete and soil. Based upon the basic features of the deformation field, a new nonlocal approach for simulating soil-concrete interfaces is proposed. It is assumed that the stress field is a function of both strain and strain gradients, and also, no relative slip occurs at the contact surface between soil and concrete. By using computational plasticity and the finite element method, static and dynamic responses of the softer material next to an interface are evaluated numerically. Comparisons are made with other numerical data. Conclusions are given on the apparent suitability of the approach.
