Various types of discontinuities have great influences on rock stability in underground excavation, as engineering disasters can be triggered by crack growth from flaws. Motivated this concern, quasi-static biaxial compression tests are conducted rock-like cement mortar materials. These examine the effect shape, orientation, and interaction pre-existing defects, representing natural or preconditioning fractures. Mechanical fracturing characteristics analyzed using stress-strain response,...
To explore the interaction between holes and fractures in defective white sandstone, uniaxial compression tests were conducted on samples with varying horizontal distances fractures. The technique known as Digital Image Correlation (DIC) was employed to analyze deformation patterns, while CT scanning technology implemented elucidate interior crack propagation features. Discrete Element Method (DEM) simulations performed investigate micro-scale fracture evolution. findings demonstrate that...
Engineering structures, including rock slopes and embankments, are vulnerable to wetting–drying cycles caused by tidal shifts rainfall, which exacerbate mechanical degradation in hole-fissured sandstone. This study investigated the effects of 0, 10, 20 on sandstone samples using uniaxial compression tests combined with digital image correlation (DIC), computed tomography (CT), scanning electron microscopy (SEM). The results revealed that progressively reduced peak strength elastic modulus...
In response to the challenges posed by long-term cyclic loading and unloading in underground rock engineering, this study systematically investigates macro- meso-mechanical mechanisms of fractured masses under conditions. We performed graded loading–unloading tests on parallel double-fractured sandstone samples with varying spatial distribution configurations. These were integrated digital image correlation (DIC) technology, fractal dimension analysis, discrete element method (DEM) numerical...
With the goal of examining micromechanics damage characteristics freeze-thaw red sandstone under influence cyclic loads, a model rock particles is developed based on Discrete Element Method numerical simulation in order to investigate and study response mechanism rocks coupling effect loads. The findings demonstrate that lower elastic modulus higher irreversible strain are driven by longer loading/unloading durations more frequent cycles. Its bearing capacity resistance deformation...
There are differences in the tensile strength of rock measured by different methods. To evaluate these strengths, direct tension test, Brazilian test with five kinds loading platens and three-point bending were conducted on Macheng granite. It indicates that (DTS) dog-bone specimens is close to cylindrical ones, but smaller than (BTS) (TPBTS). The BTS varies application platens. was obtained flat platen small-diameter steel rods. larger curved jaws platforms central angle 20°. TPBTS largest...
Studies on electrocaloric effect (ECE) play a crucial role in addressing resolving energy efficiency and environmental problems existing refrigeration technologies. Here, we report large ECE nanocomposites by incorporating ferroelectric ceramic [0.68(BaZr0.2Ti0.8O3)-0.32(Ba0.7Ca0.3TiO3)] (BCZT) into relaxor terpolymer P(VDF-TrFE-CFE) (PVTC). Our results demonstrate substantial enhancement of when BCZT concentration x is 4wt.%, including an isothermal entropy change (ΔS) 39.94 J·kg-1·K-1,...
