We describe a finite element-based method to propagate multiple fractures simultaneously. The algorithm is iterative and it simulates sub-critical quasi-static crack propagation. The matrix is homogeneous and isotropic, and behaves linear elastically. The algorithmic cornerstones are a failure crite

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

As a common practice, the compressive (negative load ratio) excursions are ignored when analyses of fatigue crack growth in metals are conducted. However, recent experimental data on fatigue crack growth with intermittent compressive load excursions have shown that the use of this assumption leads i

The fissuring mode of fracture in CANDU pressure tube material, and in particular Stage 1 crack growth (essentially flat JR curve) as observed in some irradiated compact toughness specimens has been investigated. Models are presented of the fracture process zone associated with a crack that tunnels
