Numerical analysis of plasticity induced crack closure based on an irreversible cohesive zone model

During the last years different numerical models based on node to node crack growth scheme have been employed to study the effect of plasticity induced crack closure (PICC). This paper presents a numerical analysis of PICC based on a cohesive zone model (CZM) ith with irreversible damage that employs a crack growth method coupled with cyclic plasticity at crack tip and phenomenological fracture. The CZM produces a plastic wake from volumetric...
