A rock mass containing non-persistent joints can only fail if the joints propagate and
coalesce through an intact rock bridge. Shear strength of rock mass containing non …

Step-path failure is a typical instable mode of rock slopes with intermittent joints. To gain
deeper insight into the step-path failure mechanism, six rock slopes with different intermittent …

There are only few cases where cause and location of failure of a rock structure are limited
to a single discontinuity. Usually several discontinuities of limited size interact and …

In this study, we adopt the proposed strength-based local maximum stress (SLMS) criterion
to calculate the crack propagation of tensile and shear cracks in a plate with two parallel …

To provide insight into the understanding of step-path failure in rocks, gypsum specimens
containing various configurations of preexisting flaws are used to investigate the crack …

Water existing in micro-pores has tremendous influences on the mechanical and damage
characteristics of rocks. This study aims to investigate the micro-pore water effects on the …

A coupled numerical-experimental analysis of crack propagation, cracks coalescence
produced during the cutting action of TBM disc cutters has been studied. A numerical code is …

The present research is focused on the numerical crack coalescence analysis of the micro-
cracks and cracks produced during the cutting action of TBM disc cutters. The linear elastic …

In this paper, the effect of normal load on the failure mechanism of echelon joint has been
studied using PFC2D. In the first step, calibration of PFC was undertaken with respect to the …

Pore scale variables (eg, porosity, grain size) are important indexes to predict the hydraulic
properties of porous geomaterials. X-ray images from ten types of intact sandstones and …
