Influence of different mineral grain sizes on AE source and rock mechanical properties: an example of non-homogeneous modeling

Acoustic emission statistical characteristics and fracture evolution of sandstones with different grain sizes

This study investigates the effects of grain size on the acoustic emission (AE) statistical characteristics and fracture evolution of fine-, medium-, and coarse-grained sandstones. Uniaxial compression tests with real-time AE monitoring were conducted, integrated with avalanche dynamics, fractal theory, RA-AF crack cla...

Effects of thermal treatment and grain size on the basic friction angle of granite rocks

Fracture behavior and constitutive modeling of rock-concrete contact surfaces with different roughness under freeze–thaw cycles

Experimental and Numerical Study of Water Effects on Mechanical and Fracture Behavior of Sandstone: A Case Study

Water significantly modifies rock mechanical performance and fracture characteristics through water content and water distribution. Nevertheless, the evolution laws of rock mechanical properties and underlying fracture mechanisms under variable water conditions remain incompletely clarified. In this study, uniaxial com...

Microstructural Evolution Study Under Shear Loading: A Combined CPFFT Simulation and EBSD Investigation

Metals and alloys exhibit scale‐dependent mechanical behavior governed by crystallographic slip, requiring explicit consideration of slip systems in microscale simulations of polycrystals. Crystal plasticity (CP) theory addresses this by explicitly modeling anisotropy and slip‐system interactions. In this study, the te...

Grain breakage_induced evolution of grain size distribution, pore structure, and permeability of sands under high oedometric stress

Grain breakage under high stress conditions can significantly affect the hydro-mechanical behavior of granular materials by altering grain size distribution, pore structure, porosity, and permeability. This study investigates these coupled effects in two sands with contrasting mineralogical characteristics, namely Host...
