Research on Fatigue Crack Propagation of 304 Austenitic Stainless Steel Based on XFEM and CZM
Metals, 2020 The fatigue crack propagation of 304 austenitic stainless steel was studied both by experiments and numerical simulations. Two methods were applied to simulate the crack propagation: the extended finite element method (XFEM) and the cohesive zone model ...

DesignsTo realistically simulate the entire slip-surface process from crack initiation to run-out, we couple the simplified Bishop method (LEM) with zero-thickness cohesive elements (CZM): LEM first pinpoints the critical slip circle, then CZM tracks interface ...

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).

Mixed Cohesive Zone Modeling of Interface Debonding between Propellant and Insulation
International Journal of Aerospace Engineering, 2022 High-quality interface between propellant and insulation is the strict requirement difficult to quantify in solid rocket motor. In this study, the mixed mode delamination process of propellant and insulation interface is considered in double cantilever ...
