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 (elastic / linear hardening materials interface edge prediction and elastic / power law hardening materials interface edge prediction). Finite element simulations have been conducted to accomplish quantitative examinations with the experimental results. The simulation results of stress distributions clearly show that the singular fields exist around the interface edge between the ceramic and soft metal.
