closure of rock joints

Journal of Geophysical Research: Solid Earth, 1986
Previously we verified experimentally that a generalized form of the Greenwood‐Williamson theory describing the elastic contact of two random surfaces adequately predicts the closure of joints in fused silica glass samples. Here we present a similar analysis for experiments on rock.

The effects of rock joint characteristics and normal stress level on the stiffness of rock joints

Arabian Journal of Geosciences, 2020
The present research aims to study the effects of normal stress level on the rock joint stiffness. In addition, the sample size effect was also taken into consideration. A total of 96 direct shear tests on samples with various sizes and different rock materials were conducted and extensively analyzed.

The shear strength of rock and rock joints

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1976
Abstract Rock joints exhibit a wide spectrum of shear strength under the low effective normal stress levels operating in most rock engineering problems. This is due to the Strong influence of surface roughness and variable rock strength. Conversely, under the high effective normal stress levels of interest to tectonophysicists the shear strength ...
