Extended cohesive zone model for simulation of solder/IMC interface cyclic damage process in Pb-free solder interconnects
The current formulation of stress- and energy-based cohesive zone model (CZM) is extended to account for load reversals. Cyclic degradation of solder/IMC interface properties, namely penalty stiffness, strengths and critical energy release rates follows power-law functions of fatigue cycles. Perform...
