Abstract
Characteristics of singular field around interface edge between ceramic and soft metal interlayer around the corner and the mid region of the jointed beam were investigated experimentally and theoretically. Displacement fields around the interface edge were measured using laser moire interferometer displacement anlysis technique. The measured singular field around elastic/elastic-plastic interface edge was compared with theoretical results (elastic/linear hardening material interface edge prediction and elastic/power law hardening material interface edge prediction). The controlling factors for the singular field around elastic/elastic-plastic interface edge were proposed and its validity was examined. The influence of hardening properties of interlayers on the controlling factors were investigated experimentally and theoretically.
