This study aims to explore dynamic behaviours of fracturing and damage evolution of rock
materials at the grain scale. A grain-based discrete element method (GB-DEM) is proposed …

As a state-of-the-art computational method for simulating rock fracturing and fragmentation,
the combined finite-discrete element method (FDEM) has become widely accepted since …

In this study, the dynamic fragmentation of granites at strain rates of 40–150/s is explored by
using SHPB apparatus. Two mechanical classes (ie class I and class II) are observed from …

Hydraulic fracturing has proven to be an efficient technique to enhance production in
unconventional reservoirs. Since heterogeneity is commonplace in reservoir rocks, it is vital …

We add the recent advances in particle shape representation, particle breakage modeling,
and fragmental particle size and shape acquisition to the combined finite and discrete …

In the present work, the distribution of fragments that result from a normal impact of a
temperature-controlled ice particle onto a dry, heated and rigid wall is investigated. For the …

Grain morphology has significant impacts on the mechanical behaviors of granular
materials. However, its influences on grain breakage are still poorly understood due to the …

Hydraulic fracture propagation is known to be influenced by heterogeneity; therefore, the
influence of different heterogeneity characteristics on the propagation must be studied …

It has been found that the physical and mechanical properties of rockfill materials deteriorate
when subjected to wetting–drying cycles. Previous studies have mainly focused on the …

The earthquake-induced rock avalanche in the Tangjia Valley was the most notable
geological disaster triggered by the Lushan earthquake in 2013. In order to investigate the …
