We have determined the constitutive parameters for frictional sliding of initially bare surfaces of Westerly granite, using a recently developed high …
WebNov 1, 1970 · Frictional sliding on ground surfaces of granite, angle of sliding planes 30° and 45°, was investigated as a function of confining pressure. Over the normal stress range of 2–12 kb, the static frictional shear stress τs follows the relationship τs = 0·5 + 0· σn and the kinetic frictional shear stress τk was calculated to be τk = 0 ...

WebApr 11, 2024 · Low-angle normal faults (LANFs) are poorly understood, as their slip at <30° dips appears inconsistent with Byerlee friction and Andersonian stresses. Rider blocks are fault slices formed when the uppermost part of a LANF is abandoned in favor of a new, steeper fault. Mohr-Coulomb modeling of rider blocks can constrain fault frictional and ... bythewaycom.orgWebThe deformational characteristics of two limestones, one gabbro, and one dunite have been investigated as a function of confining pressure.
