Crack damage stress in fully saturated rocks: a new detection procedure [PDF]

Geoscientific Instrumentation, Methods and Data Systems
Crack damage stress, also known as the onset of dilatancy, indicates the long-term strength of a rock as it describes the transition from the stable to the unstable crack growth phase under loading.
