Strong embedded discontinuities for simulating fracture in quasi-brittle materials [PDF]
, 2011 In this paper embedded strong discontinuities are used to model discrete cracking in materials like concrete. In the approach followed a discontinuous displacement field is considered and the deformation is localized at a surface of zero width.

Crack growth resistance in nuclear graphite [PDF]
, 2002 R-curve behaviour is often used for evaluating crack growth resistance in quasibrittle materials but few studies have focused on polycrystalline graphite. In this study, R-curve behaviour in three commercial grade nuclear graphites, of varying structure

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 ...

Influence of grain structure and slip planarity on fatigue crack growth in low alloying artificially aged 2xxx aluminium alloys [PDF]
, 2007 The fatigue crack growth behaviour under constant amplitude loading of three low alloying artificially aged 2xxx aluminium alloys with distinct microstructures is analysed. Fatigue crack growth tests show a correlation between fatigue performance and the

A numerical study of crack shielding and deflection under extensive plasticity [PDF]
, 2009 Experimentally observed crack deflection events in multi-layered material systems, occurring even under pure mode-I loading, are here simulated and explained through elasto-plastic finite element modelling.

Effects of graphite nodules on crack growth behaviour of austempered ductile iron [PDF]
, 2007 Austempered ductile iron (ADI) is a candidate material for camshafts, where however, the early stages of fatigue damage are of major concern during service.

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 ...

Evaluation of the intrinsic crack growth rates of weld joints [PDF]
, 2011 A method is presented for evaluating weld intrinsic fatigue crack growth rate (FCGR) by excluding the influence of residual stresses. The method is potentially useful for predicting crack growth lives of structural components using measured FCGR data ...
