Paper presented at the 52nd U.S. Rock Mechanics/Geomechanics Symposium, June 17–20, 2018
Paper Number: ARMA-2018-1072
... adequate knowledge of the geometric characteristics evolution in deformable rough fractures is necessary to understand the mechanical and hydraulic behaviors of the fractured rock mass. In past decades, the surface geometric characteristics, including Joint roughness characteristics (JRC), peak asperity...

Paper presented at the 47th U.S. Rock Mechanics/Geomechanics Symposium, June 23–26, 2013
Paper Number: ARMA-2013-438
... caused by variations in fracture aperture. Two different rough fracture geometries were used and are compared to smooth-walled converging and diverging synthetic fractures. The variation in aperture along a swarm’s transport path exerted a strong influence swarm evolution and, in many cases, enhanced...

... are accurate across a range of conditions (400-500°C, 20-150 MPa, and mean particle diameter of 3-120 m). The model is applied to rough fractures to illustrate important feedbacks between elastic deformation and chemical-mechanical creep. Probing analyses of environments typical of enhanced geothermal...

Paper presented at the The 42nd U.S. Rock Mechanics Symposium (USRMS), June 29–July 2, 2008
Paper Number: ARMA-08-159
... across a fracture can be used to monitor changes in subsurface stresses. Usually, in such applications, only the stress acting normally to a fracture is considered, which results in large changes in the scattering of seismic waves. However, when a nominally planar, compliant, rough fracture is sheared...
