The current literature on three-dimensional (3D) needle-punched composites tends to
address the aspects of preforms fabrication and composites characterization respectively …

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 …

This study numerically investigates the influence of material heterogeneity on the strength
and deformation behavior and the associated microcracking process of a felsic crystalline …

A grain‐based Universal Distinct Element Code model was developed to generate a
deformable polygonal grain‐like structure to simulate the microstructure of brittle rock. It …

Cracking and coalescence behavior in a rectangular rock-like specimen containing two
parallel (stepped and coplanar) pre-existing open flaws under uniaxial compression load …

Understanding the strain rate effects on cement-based materials are important for accurately
modeling concrete structure damage to high-velocity impact and blast loads. This paper …

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

This research presents a new heterogeneity index to describe micro-geometric
heterogeneity induced by grain size variation in intact rock. Micro-geometric heterogeneity is …

A distinct element grain-based method (GBM) was developed to simulate the microstructure
of rock-like materials. Using this method, a UDEC-GBM model can be readily constructed …

Conventional water-based fracturing treatments may not work well for many shale gas
reservoirs. This is due to the fact that shale gas formations are much more sensitive to water …
