The microstructure and mineralogy of volcanic rocks is varied and complex, and their
mechanical behaviour is similarly varied and complex. This review summarises recent …

Many of the earliest laboratory studies of the brittle-ductile transition were on porous rocks,
with a focus on the evolution of failure mode from brittle faulting to cataclastic flow with …

For a full understanding of the cracking processes in granite, uniaxial compression tests are
conducted on prismatic specimens with pre-existing flaws, and digital imaging and AE …

It is difficult to accurately visualize internal structure and characterize progressive fracture
process during rock failure due to the heterogeneous and opaque features of rock. This …

One of the first courses I taught at Stanford was Advanced Soil Mechanics. The course title
was accurate in the beginning, but the contents gradually became more and more about …

This monograph deals with the part of the field of experimental rock deformation that is
dominated by the phenomena of brittle fracture on one scale or another. Thus a distinction …

Deformation bands are the most common strain localization feature found in deformed
porous sandstones and sediments, including Quaternary deposits, soft gravity slides and …

We conducted an extensive suite of true triaxial experiments in two porous sandstones,
Bentheim (porosity≈ 24%) and Coconino (17.5%). Our experiments demonstrate that failure …

Conventional triaxial compression and “reducing confining pressure” experiments were
carried out for red sandstone by an MTS815 Flex Test GT rock mechanics experimental …

The mechanical behavior of clay shales is of great interest in many branches of geo-
engineering, including nuclear waste disposal, underground excavations, and deep well …
