A damage-based cohesive model is developed for simulating crack growth due to fatigue loading. The cohesive model follows a linear damage-dependent traction-separation relation coupled with a damage evolution equation. The rate of damage evolution is characterized by three material parameters corres
## Research highlights βΊ Cohesive zone elements allow to model fatigue crack initiation and growth. βΊ An algorithm reducing extensively the simulation time with little loss of accuracy was developed. βΊ The variability inherent in the fatigue life was assessed using a random field model. βΊ Both crac
