Many engineering technologies require the use of components consisting of interfacial joints which are inevitably subjected to cyclic loading during service time. In this research, the fracture analysis of the interfacial brazed joints is considered using the Cohesive Zone Model (CZM) as the joint constitutive relation to be coupled with a proper damage evolution law to include all degradation mechanisms. The outcome of this research will be directed to the reliability study of the laminated casting dies subjected to high internal molten metal pressure and thermal stresses during each service cycle.
