AB - In this pape,r two formulations for introducing fatigue damage into cohesive elements have been examined to determine their mesh sensitivity and numerical stability in mode I. A simple, non-FE model has been used to quickly assess a wide range of parameters associated with the fatigue degradation routines developed for cohesive elements. The model has been used to explore the sensitivity of two fatigue degradation strategies to changes in key parameters. For small element and cycle increments, both models predict the fatigue crack growth rate accurately for various applied loads where the Paris law is valid. However the models exhibit significant mesh sensitivities. The analysis has shown that in order to obtain a numerically stable algorithm, the models need to be improved.
