Crack tip fields in elastic-plastic and mixed mode I+II+III conditions, finite elements simulations and modeling [PDF]
Fracture and Structural Integrity, 2015 This paper is devoted to the analysis of the load path effect on I+II+III mixed mode fatigue crack propagation in a 316L stainless steel. Experiments were conducted in mode I+II and in mode I+II+III.

Crack paths in composite materials [PDF]
Engineering Fracture Mechanics, 2010 Composites are often exposed to harsh loading conditions. This may lead to crack formation and propagation. In this paper an algorithm is described to predict the path of pre-existing cracks in homogeneous materials, based on an incremental approach. The approach is shown to also deal with the highly heterogeneous behaviour of periodically distributed ...

Crack paths in soft thin sheets
Fracture and Structural Integrity, 2019 Highly deformable materials (elastomers, gels, biological tissues, etc.) are ubiquitous in nature as well as in technology. The understanding of their flaw sensitivity is crucial to ensure a desired safety level.

Procedia Structural Integrity, 2018 Abstract Next to the shape of a growing crack, it is of importance to predict the initiation of new cracks, especially in structures with stress concentrations due to e.g. holes or notches. In the past, different criteria for crack initiation have been discussed. Furthermore, cracks growing in the vicinity of such stress concentrations in general are

Fatigue crack growth of aluminium alloy 7075-T651 under non-proportional mixed mode I and II loads [PDF]
Fracture and Structural Integrity, 2016 This study aims to investigate fatigue growth behaviour in AA7075-T651 under non-proportional mixed mode I and II loads. Fatigue tests were performed under cyclic tension and torsion using a thin-walled tubular specimen with a key-hole style crack ...
