Journal ArticleDOI
Subcritical crack growth in geological materials
TL;DR: A review of the experimental data on subcritical crack growth in geological materials is presented in this article, where the main parameters describing subcritical cracking growth are the critical stress intensity factor Kc, the sub critical crack growth limit Ko, and the relationship between Ko and Kc.
Journal ArticleDOI
Subcritical crack propagation in rocks: theory, experimental results and applications
TL;DR: In this article, a fracture mechanism map for quartz is presented which was constructed using a combination of theoretical insights and experimental data, with particular emphasis on the influence of chemical effects on fracture controlled by preexisting cracks (stress corrosion).
Journal ArticleDOI
Fracture toughness and subcritical crack growth during high-temperature tensile deformation of Westerly granite and Black gabbro
Philip G. Meredith,BK Atkinson +1 more
TL;DR: In this article, double torsion testing was used to determine catastrophic and subcritical crack propagation parameters for pre-cracked specimens of Westerly granite and Black gabbro under a number of environmental conditions.
Journal ArticleDOI
Temporal variations in seismicity during quasi-static and dynamic rock failure
TL;DR: In this article, a comprehensive model is presented which can explain temporal fluctuations in seismic b-values in the period leading to mechanical failure in terms of the underlying physical processes of time-varying applied stress and stress corrosion-enhanced crack growth under conditions of constant strain rate.

Stress corrosion and acoustic emission during tensile crack propagation in Whin Sill dolerite and other basic rocks
Philip G. Meredith,BK Atkinson +1 more
TL;DR: In this article, double torsion tests in ambient air and liquid water have been used to establish critical stress intensity factors (KIc) and stress intensity factor (KI)•crack velocity diagrams for propagation of single tensile cracks in Whin Sill dolerite and Ralston Intrusive.
