Journal ArticleDOI
TL;DR: The mechanisms by which cracks extend from flaws in brittle materials subjected to compressive loads are presented in this paper, where they are restricted to single-phase, dense materials in order to provide a model amenable to analysis and experimental confirmation.

Journal ArticleDOI
TL;DR: In this article, the initiation of crack growth under a combination of opening and anti-plane shearing mode loading is considered, and it is shown that such cracks do not grow through a continuous evolution of the crack surface.
Abstract: The initiation of crack growth under a combination of opening and anti-plane shearing mode loading is considered in this paper. It is shown that such cracks do not grow through a continuous evolution of the crack surface. Rather, an abrupt fragmentation or segmentation of the crack front is generated. Through experimental observations and a theoretical model, we postulate a relationship between the scale of the fragmentation and the mode mix.

Journal ArticleDOI
TL;DR: In this paper, the authors investigate the mixed mode fatigue crack growth threshold behavior of mild steel and show that the expected tendency to Mode I crack growth showed as an initial directional discontinuity followed by a smooth rotation of the crack front until it was almost perpendicular to the specimen sides.
