New CZM for Interfacial Crack Growth [PDF]
Mathematical Problems in Engineering, 2017 The cohesive zone model (CZM) has been widely used for numerical simulations of interface crack growth. However, geometrical and material discontinuities decrease the accuracy and efficiency of the CZM when based on the conventional finite element method (CFEM).
