✦ Synopsis

In this work a cohesive zone model is developed to simulate fatigue crack propagation along bonded interfaces. The model is implemented by means of the USDFLD subroutine in the commercial software Abaqus. In particular, the crack growth increment is translated into a damage increment per cycle in the cohesive elements ahead of the crack tip. The computation of the strain energy release rate, not available in output for cohesive elements in Abaqus, was specifically implemented.
