... Abstract This paper investigates the progressive shear behavior and asperity degradation of rock joints in the direct shear test using PFC2D. PFC is a discrete element code in which the intact material is represented by assemblies of circular particles bonded together. Traditionally, joints...

... affecting shear behavior and consequently generated AE signals during direct shear test of rock joints. In the first method several samples were tested under normal stress of 0.5, 1 and 2MPa respectively. In the second method, normal stress was changed from 0.5 to 2MPa in the residual section of the same...

... The authors have developed a theoretical model for the shear behavior of rock joints under several confining conditions. The model considers the influence of the normal confining conditions, the material strength of the intact rock, the basic friction angle, and joint surface roughness...
