Chinese Journal of Mechanical Engineering, 2023 To explore the influence of path deflection on crack propagation, a path planning algorithm is presented to calculate the crack growth length. The fatigue crack growth life of metal matrix composites (MMCs) is estimated based on an improved Paris formula.

Hydraulic Fracture Propagation Near the Cavity in a Poroelastic Media
Applied 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.

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

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 ...

Quasicontinuum simulation of fracture at the atomic scale [PDF]
, 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.
