TL;DR: In this paper, the authors investigated the relationship between energy transformation and coal failure by conventional triaxial compression tests using five different confining pressures and found that the peak strength increased with increasing confining pressure, but the critical damage variable was almost invariant.

TL;DR: In this paper, the authors employed 3D frozen stress and photoelastic technologies to characterize and visualize the stress distribution within the fractured coal under uniaxial compression and 3D printed model presented the fracture structures identical to those of the natural coal.

TL;DR: In this paper, digital image processing methods integrated with fractal theory were applied to analyze images of rock slices obtained from industry CT, elucidating the characteristics of rock pore structure and the relationship between porosity and fractal dimensions.

TL;DR: In this article, the authors present a novel integration of X-ray computed tomography (CT) imaging, 3D printing, and photoelastic testing for the transparentization and visualization of the aggregated structure and stress field of heterogeneous geomaterials.

TL;DR: In this paper, a novel approach that incorporates computed tomography and servo-controlled triaxial loading techniques to accomplish the laboratory in situ observation of the continuous evolution of 3D fracture networks inside coal samples which were subject to confining pressures and axial compressive loads.
