Slightly curved or kinked cracks
Brian Cotterell,James R. Rice +1 more
TL;DR: In this paper, a solution for the elastic stress intensity factors at the tip of a slightly curved or kinked two-dimensional crack is presented for 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].

Crack deflection: Implications for the growth of long and short fatigue cracks
TL;DR: In this paper, a simple elastic deflection model is developed to estimate the growth rates of nonlinear fatigue cracks subjected to various degrees of deflection, by incorporating changes in the effective driving force and in the apparent propagation rates.

Crack paths in plane situations-II. Detailed form of the expansion of the stress intensity factors.
M. Amestoy,Jean-Baptiste Leblond +1 more
TL;DR: In this paper, the authors established the general form of the expansion of the stress intensity factors in powers of the crack extension length, for a crack propagating in a two-dimensional body along an arbitrary kinked and curved path.

Characteristics of brittle fracture under general combined modes including those under bi-axial tensile loads
TL;DR: In this article, the fracture initiation characteristics under general combination of the opening mode, sliding mode and tearing mode were investigated both theoretically and experimentally. And the experimental fracture strengths were compared with those predicted by the fracture criteria which are represented in terms of: (1) maximum tangential stress, [σgq]max, extended to general combined modes, (2) maximum energy release rate at the propagation of a small kinked crack, [Gk(γ)]max, and (3) newly derived maximum EE at the initiation of an EH burst, [

Stress Singularities Resulting From Various Boundary Conditions in Angular Corners of Plates in Extension
TL;DR: In this paper, the authors investigated three boundary conditions on the radial edges: free-free, clamped-clamped, and clamped free, and showed that the free free extensional plate behaves locally at the origin exactly the same as a clampedclamped plate in bending, independent of Poisson's ratio.
