Abstract
Experimental and theoretical analyses have been developed to analyze the path of a near-interfacial crack running nearly parallel to a ceramic/metal interface in a bimaterial layered structure. In the present study, the trajectories of cracks, initiated in the ceramic at varying distances from such interfaces, are investigated both experimentally and numerically. General trends in expected behavior, specifically that cracks propagate along a path defined by K π=0, and that cracks are attracted to or repelled from a layer if it is relatively more or less compliant, respectively, are confirmed.
