A field-enriched finite element method for brittle fracture in rocks subjected to mixed mode loading
TL;DR: In this article, a field-enriched finite element method is proposed to simulate the crack propagation and coalescence of brittle rocks subjected to mixed mode loading, and three semi-circular bending (SCB) configurations are employed to investigate the effect of different factors on the fracture patterns under mixed-mode loading.

Theoretical and numerical models of rock wing crack subjected to hydraulic pressure and far-field stresses
TL;DR: In this paper, the authors studied the evolution laws of SIF at the wing crack tip subjected to hydraulic pressure and far-field stresses, theoretically and numerically, based on the previous proposed wing crack models without considering hydraulic pressure.

Effects of arbitrary holes/voids on crack growth using local mesh refinement adaptive XIGA
TL;DR: In this article, a locally refined (LR) B-splines extended isogeometric analysis (XIGA) was applied to evaluate the stress intensity factors (SIFs), and the direction of crack growth was determined with the maximum circumferential stress criterion.

On the Stress Distribution at the Base of a Stationary Crack
TL;DR: In this article, it was shown that at the base of the crack in the direction of its prolongation, the principal stresses are equal, thus tending toward a two-dimensional (two-dimensional) hydrostatic tension.
