Characteristics of singular fields around an interface edge between ceramic and soft metal interlayer around the mid region of the jointed beams were investigated experimentally and theoretically. Displacement fields around the interface edge were measured using laser moire interferometer displacement analysis technique. The measured singular fields around the elastic/elastic-plastic interface edge were compared with theoretical results (linear hardening prediction and power law hardening prediction). Finite element simulations have been conducted to acomplish quantitative examinations with the experimental results. The simulation results clearly show that the singular fields can be predicted using rigid/elastic-plastic material interface model. A controlling factor for the evolution of singular fields around the elastic/elastic-plastic materials interface edge was proposed and its validity was examined.
