Numerical implementation of a fatigue cohesive zone model and simulation of mode I crack propagation of adhesively bonded composites

摘要

The purpose of this work is to develop a computational method for adhesively bonded composite structures lifetime assessment. A cohesive zone model - based formulation including fatigue damage is selected. The model is implemented in the finite element software Abaqus through user subroutine. Numerical simulations are subsequently performed for the mode I crack propagation case. Validation of available experimental data for both quasi-static and high-cycle fatigue tests is successfully achieved.
