Crack paths under mixed mode loading [PDF]
, 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 ...

Cruciform specimens for the determination of crack growth behaviour in biaxial stress fields: calculation of K-factors [PDF]
MATEC Web of Conferences, 2019 The aim of this study is to propose a simplified calculation of the Mode I stress intensity factor K for the cruciform specimen design proposed by Brown and Miller.

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.

Finite-distance singularities in the tearing of thin sheets [PDF]
, 2011 We investigate the interaction between two cracks propagating in a thin sheet. Two different experimental geometries allow us to tear sheets by imposing an out-of-plane shear loading.

A variational model of fracture for tearing brittle thin sheets [PDF]
, 2018 Tearing of brittle thin elastic sheets, possibly adhered to a substrate, involves a rich interplay between nonlinear elasticity, geometry, adhesion, and fracture mechanics.

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 ...

Some practical crack path examples [PDF]
Fracture 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.

Attractive and repulsive cracks in a heterogeneous material
, 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.
