Rock fracture under upper crustal conditions is driven not only by applied stresses, but also
by time-dependent, chemically activated subcritical cracking processes. These subcritical …

In the upper crust, the chemical influence of pore water promotes time dependent brittle
deformation through sub‐critical crack growth. Sub‐critical crack growth allows rocks to …

The micromechanical damage mechanics formulated by Ashby and Sammis, 1990,“The
Damage Mechanics of Brittle Solids in Compression,” Pure Appl. Geophys., 133 (3), pp. 489 …

We develop a unifying framework to quantify rate‐dependent deformation in the brittle field
and establish links between the microscale time‐dependent crack growth processes and the …

Effects of thermal crack damage on the rupture processes of a fine‐grained granite were
investigated under triaxial stress, under water (wet) and argon gas (dry) saturated …

Large earthquakes are the product of elastic stress that has accumulated over decades to
centuries along segments of active faults. Assuming an elastic crust, one can roughly …

Geomaterials contain numerous cracks whose interaction affects the macroscopic
mechanical properties of the materials significantly. We propose a mechanical model of …

Geophysical observations show a dramatic drop of seismic wave speeds in the shallow off-
fault medium following earthquake ruptures. Seismic ruptures generate, or reactivate …

Subcritical crack propagation and rock creep deformation are the main factors affecting the
long-term stability and strength characteristics of rocks under hydro-mechanical coupling …

Failure of brittle materials containing embedded three dimensional pre-cracks and subjected
to uniaxial compressive and tensile loading is considered here. The sliding crack (wing …
