Quasi-static fault growth and shear fracture energy in granite
TL;DR: In this article, the failure process in a brittle granite sample can be stabilized by controlling axial stress to maintain a constant rate of acoustic emission, and the post-failure stress curve can be followed quasi-statically, extending to hours the fault growth process.

The transition from brittle faulting to cataclastic flow in porous sandstones: Mechanical deformation
TL;DR: In this article, the authors investigated the inelastic and failure behavior of six sandstones with porosities ranging from 15% to 35% and used a broad range of effective pressures to investigate the transition in failure mode from brittle faulting to cataclastic flow.
