Paper Abstract

By use of extended finite element analysis method, a calculation of J-integral for interface crack on Micro-arc Oxidation(MAO) ceramic coating on aluminum alloy was conducted. The feasibility of using J-integral as a fracture parameter to characterize the interfacial fracture toughness is discussed. The relation between J-integral and length of interface crack, thickness of ceramic coating is studied. Analysis result indicates that with the expansion of the interface crack length, resistance bi-material interface enhancements, and interfacial fracture toughness enhances, the J-integral increases with the increase of crack length. When the thickness of the ceramic coating is upon 40μm-100μm, interfacial fracture toughness is better. J-integral value shows a decreasing trend with the increase of the thickness of the ceramic coating.
