Kinked crack in a bending trapezoidal plate
International Journal of Fracture, 2001The interaction problem of a kinked crack and the edges of a bending trapezoidal plate which takes the effects of transverse shear deformation into account is presented. The research method is based upon the complex potential technique of Muskhelishvili using conformal mapping.

Energy release rate and crack kinking
International Journal of Solids and Structures, 1981Abstract A closed form solution is presented for the energy release rate at the onset of kinking of a straight crack in an infinite elastic medium subjected to a predominantly Mode I loading. The solution is accurate to the second order of kink angle and is carried out by the method which models the kink as a continuous distribution of infinitesimal ...

Kinked cracks in anisotropic elastic materials
International Journal of Fracture, 1998The problem of a kinked crack is analysed for the most general case of elastic anisotropy. The kinked crack is modelled by means of continuous distributions of dislocations which are assumed to be singular both at the crack tips and at the kink vertex. The resulting system of singular integral equations is solved numerically using Chebyshev polynomials

Initiation, Propagation, and Kinking of an In-Plane Crack
Journal of Applied Mechanics, 1988Consider an infinite linear elastic body containing a semi-infinite crack loaded by a longitudinal stress pulse parallel to the crack face. After the stress wave strikes the crack at time t = 0, the stress gradually intensifies at the crack tip. At some finite delay time tt, the crack begins to extend straight ahead with constant speed vo.

Kinking of an interface crack in an orthotropic bimaterial
Fatigue & Fracture of Engineering Materials & Structures, 2013ABSTRACTWe investigated the asymptotic problem of a kinked interface crack in an orthotropic bimaterial under in‐plane loading conditions. The stress intensity factors at the tip of the kinked interface crack are described in terms of the stress intensity factors of the interface crack prior to the kink combined with a dimensionless matrix function ...

A bifurcation study of crack initiation and kinking
The European Physical Journal B, 2013Based on a two-dimensional atomistic model, we study the bifurcation associated with crack propagation and kinking. In the study, the varying parameter is the tensile and shear strain applied at the boundary. Both mode-I and mixed mode-I/II loading are considered.

Criteria for kinking out of interface crack
Engineering Fracture Mechanics, 1994Abstract Three kinds of criteria for kinking out of the interface crack between dissimilar materials are discussed. Their validity and applicability are examined by comparison with the experimental results from two types of specimens. As the results G max criterion based on energy release rate shows best prediction on both the kink initiation ...

On singular integral equations for kinked cracks
International Journal of Fracture, 1986Chebyshev polynomial techniques for solution of singular integral equations leading to square root singularities at the ends of the interval of integration are studied. It is shown that the results are less accurate when a singularity, albeit a weak one, appears between the interval ends. Typical examples are problems involving kinked cracks.
