## Research highlights ► Cohesive zone elements allow to model fatigue crack initiation and growth. ► An algorithm reducing extensively the simulation time with little loss of accuracy was developed. ► The variability inherent in the fatigue life was assessed using a random field model. ► Both crac
Abstraet--A new method of fatigue analysis for components is outlined; the novelty of the method is that it uses fracture mechanics concepts without introducing a crack into the component. Stress concentrations are analysed by examining their stress fields and comparing these with the stress fields
