Slightly curved or kinked cracks
International Journal of Fracture, 1980A solution is presented for the elastic stress intensity factors at the tip of a slightly curved or kinked two-dimensional crack. The solution is accurate to first order in the deviation of the crack surface from a straight line and is carried out by perturbation procedures analogous to those of Banichuk [1] and Goldstein and Salganik [2, 3 ...

Abstract This paper attempts to provide a comprehensive summary of results on the following topics relating to crack kinking and curving: (a) Stress intensity factors for kinked cracks under combined loading; (b) applicability of Irwin's energy-release rate formula to kinked cracks; and (c) reasons behind crack kinking and curving.

International Journal of Fracture, 1992
The integral equation of the kinked interface crack is solved numerically. The values of K I, K II and G for an interface crack with an infinitesimal kink are used to predict the kinking angle for two different material combinations under uniaxial tension.

Crack kinking in a piezoelectric solid
International Journal of Solids and Structures, 1999The authors investigate the problem of crack kinking in a piezoelectric solid, using Stroh formalism. The kink of the crack is modeled by a continuous distribution of edge dislocations and electric dipoles, and the fundamental solution for the crack kinking is provided by the interation between a piezoelectric dislocation and a traction-free crack.

Crack Kinking Criterion for Bimaterial System
New and Emerging Computational Methods: Applications to Fracture, Damage, and Reliability, 2002This paper is aimed to find out a suitable criterion for predicting the interfacial crack in the bimaterial system. An investigation was undertaken into the interfacial crack kinking phenomena in a bimaterial specimen of epoxy and aluminum alloy using a combination of experimental method and numerical simulation.

Two dimensional numerical simulation of crack kinking from an interface under dynamic loading by time domain boundary element method [PDF]
International Journal of Solids and Structures, 2007 The hybrid time-domain boundary element method, together with the multi-region technique, is applied to simulate the dynamic process of propagation and/or kinking of an interface crack in a two-dimensional bi-material.

Kinked cracks in an anisotropic material
Engineering Fracture Mechanics, 1991Abstract A kinked semi-infinite crack in an anisotropic material is analyzed. The stress intensity factors of the kinked crack tip are expressed in terms of those associated with the main crack prior to kinking. The asymptotic stress field around the crack tip is derived for the degenerate case in which the two complex parameters of the anisotropic ...
