✦ Synopsis

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 crack initiation and propagation are described by the same model.

A new probabilistic model of fatigue crack growth is constructed in which the parameters are explicit functions of the stress intensity factor. There are two versions of this model. These models are applied to a set of fatigue crack growth data. Some comments are offered on the implications of these

In this paper, the extended finite element method (XFEM) is used for a discrete crack simulation of concrete using an adaptive crack growth algorithm. Different criteria for predicting the direction of the extension of a cohesive crack are investigated in the context of the XFEM. The robustness of t
