With the growing development and utilization of underground space and resources, rock
masses exposed to high stresses and pore pressure, large temperature changes, and …

Material behavior and microstructure geometries at small scales strongly influence the
physical behavior at higher scales. For example, defects like cracks and dislocations evolve …

Aiming to solve, in a unified way, continuous and discontinuous problems in geotechnical
engineering, the numerical manifold method introduces two covers, namely, the …

A micro-mechanical based numerical manifold method (NMM) is proposed in this study to
investigate the micro-mechanisms underlying rock macroscopic response and fracture …

The extended finite element method (XFEM) has achieved unprecedented success in crack
analysis. However, challenges still remain for a multiple crack simulation. One issue is the …

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 …

We propose a coarse-graining technique to reduce a given atomistic model into an
equivalent coarse grained continuum model. The developed technique is tailored for …

This paper extends the numerical manifold method (NMM) for footwall slope stability
analysis. A fracturing algorithm based on the Mohr–Coulomb criterion with a tensile cutoff is …

An improved XFEM (IXFEM) is developed for the analysis of arbitrary multiple crack
initiation, propagation, and interaction in two-dimensional (2-D) elastic solids. The proposed …

Grouting is a widely used approach to reinforce broken surrounding rock mass during the
construction of underground tunnels in fault fracture zones, and its reinforcement …
