Mineral grain size heterogeneity is one of the fundamental reasons leading to differences in
rock mechanical behaviours. Several indices have been proposed to quantify grain size …

Numerical back analysis is a valuable tool available to rock mechanics researchers and
practitioners. Recent studies related to back analysis methods focused primarily on …

Rock materials are typically heterogeneous. Traditional digital image processing (DIP)
technology and the grain-based model (GBM) method are difficult to apply to engineering …

Mine tailings (MTs) are ore residuals after valuable metals were extracted during mineral
processing, which can be reused to produce the geopolymer concrete for construction and …

As a typical heterogeneous material, the macroscopic mechanical properties of rocks are
influenced by factors, such as the type, size, and spatial distribution of internal mineral …

To study the effect of loading rate on the mechanical properties of salt rock, uniaxial
compression tests and acoustic emission tests at different loading rates were carried out on …

Reliable prediction of the rock fracturing process is a challenging issue in exploitation of
deep earth resources in which artificial creation of complex fracture networks is employed …

Based on a two-scale tessellation technique in Neper, a 3DEC-GBM modeling approach
considering inter-and intra-grain contact failures is proposed to study brittle rock failure …

A particle-based discrete element model combined with digital image processing to take into
account the grain geometry and size distribution is used to investigate the mechanical and …

The emergent macroscopic behaviors of Bonded Block Models (BBM) are governed largely
by the properties assigned to their three components–blocks, contacts and zones (blocks …
