Influence of corrosion and creep on intergranular fatigue crack path in 2XXX aluminium alloys [PDF]

open access: yes, 2010
In this paper, two examples of the influence of time-dependent processes on crack path in two 2XXX aluminium alloys are presented. The first example is concerned with corrosion–fatigue crack growth resistance of a 2024 T351 alloy cracked in the S–L ...

Hydraulic Fracture Propagation Near the Cavity in a Poroelastic Media

open access: yesApplied Sciences, 2021
In this paper, we investigate the problem of the propagation of hydraulic fractures in a poroelastic medium that has a circular cavity. The research was conducted using the extended finite element method (XFEM) implemented in the ABAQUS software package.

Fatigue crack growth in thin notched woven glass composites under tensile loading. Part I: experimental [PDF]

open access: yes, 2011
Helicopter blades are made of composite materials mainly loaded in fatigue and have normally relatively thin skins. A through-the-thickness crack could appear in these skins.

Quasistatic crack evolution for a cohesive zone model with different response to loading and unloading: a Young measures approach [PDF]

open access: yes, 2009
A new approach to irreversible quasistatic fracture growth is given, by means of Young measures. The study concerns a cohesive zone model with prescribed crack path, when the material gives different responses to loading and unloading phases.

Fatigue crack growth in a laser shock peened residual stress field [PDF]

open access: yes, 2019
Laser Shock Peening is a surface treatment technique used in the aerospace sector to increase fatigue life, as well as resistance to fretting fatigue and stress corrosion cracking.

Quasicontinuum simulation of fracture at the atomic scale [PDF]

open access: yes, 1998
We study the problem of atomic scale fracture using the recently developed quasicontinuum method in which there is a systematic thinning of the atomic-level degrees of freedom in regions where they are not needed.

Crack paths under mixed mode loading [PDF]

open access: yes, 2008
Long fatigue cracks that initially experience mixed mode displacements usually change direction in response to cyclic elastic stresses. Eventually the cracks tend to orient themselves into a pure mode I condition, but the path that they take can be ...

Attractive and repulsive cracks in a heterogeneous material

open access: yes, 2008
We study experimentally the paths of an assembly of cracks growing in interaction in a heterogeneous two-dimensional elastic brittle material submitted to uniaxial stress.
