... same plane. More realistically shear stress acting on a plane may lead to strain (dilation or compaction) perpendicular to the plane. If we make the convenient, but not necessarily correct, approximation that the rock behaves in an orthotropic manner, then the number of independent terms in the...

Firstly, the rock samples containing the pre-existing weakness planes were analyzed according to the curves of volumetric strain versus stress difference acquired by laboratory experiment. Secondly, the effective normal stress and shear stress of weakness planes were calculated by the...

The verification shows that the linearized Barton's model can capture the nonlinearity in the shear stress-displacement and in the...

... Abstract Falling head flow tests have been performed to determine the hydraulic conductivity of tension-induced fractures while under normal and shear stresses for eight rock types. The joint roughness coefficients are determined and used to calculate the mechanical aperture. The shear stress...

A paradoxical feature of the fan-mechanism is the ability to develop dynamically new faults in intact rocks at shear stress levels significantly less than frictional strength. Another important feature is that for the...
