Crack path dependence on inhomogeneities of material microstructure [PDF]

open access: yesFracture and Structural Integrity, 2012
Crack trajectories under different loading conditions and material microstructural features play animportant role when the conditions of crack initiation and crack growth under fatigue loading have to beevaluated.

Crack paths in composite materials [PDF]

open access: yesEngineering 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 ...

Predicting the crack path in a wedge under a concentrated tensile force by means of variational principle

open access: yesFracture and Structural Integrity, 2019
Variational principle of brittle fracture mechanics is employed to predict the crack path in an infinite wedge under a concentrated tensile force. The weight function in basic equation of variational problem is assumed to be proportional to the maximum ...

Crack tip fields in elastic-plastic and mixed mode I+II+III conditions, finite elements simulations and modeling [PDF]

open access: yesFracture 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.

Data-driven model based on the simulation of cracking process in brittle material using the phase-field method in application

open access: yesComptes Rendus. Mécanique, 2020
Numerical simulations and parametric studies of notched rectangular specimens subjected to dynamic tensile loads were performed. The simulations were based on two-dimensional finite element analysis to predict the brittle fracture path using the phase ...

Some practical crack path examples [PDF]

open access: yesFracture and Structural Integrity, 2007
It is well known that many engineering structures and components, as well as consumer items, contain cracks or crack-like flaws. It is widely recognised that crack growth must be considered both in designand in the analysis of failures.

Crack paths in soft thin sheets

open access: yesFracture 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.

Crack Path Prediction in Anisotropic Brittle Materials [PDF]

open access: yesPhysical Review Letters, 2005
A force balance condition to predict quasistatic crack paths in anisotropic brittle materials is derived from an analysis of diffuse interface continuum models that describe both short-scale failure inside a microscopic process zone and macroscopic linear elasticity.

Fatigue crack growth of aluminium alloy 7075-T651 under non-proportional mixed mode I and II loads [PDF]

open access: yesFracture 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 ...

Small crack growth behavior in selective laser melted TC4 alloy

open access: yesCailiao gongcheng, 2023
The three-dimensional small crack growth behavior of selective laser melting (SLM) TC4 alloy was investigated by in-situ observation fatigue test method, and the long crack growth curve was measured by load reduction method under the same experimental ...
