Compressive Strength Variations Of Fracture Specimens Under Different In this investigation, we study the failure mode and seepage law of confined water with fractured rock mass in the coal seam floor under stress and seepage conditions. To investigate the mechanical properties and fracture mechanisms of rock like specimens containing a hole under water–rock interaction, uniaxial compression tests were conducted on five groups of rock like specimens with different water contents (0%, 0.41%, 0.81%, 1.22%, and 1.62%). a high definition imaging system was used to record the failure process, and scanning electron microscopy (sem.
Compressive Strength Of Different Fracture Angles Under Different This study aims to investigate the effects of different fracture angles on the mechanical behavior and failure modes of limestone concrete specimens under compression shear loading conditions. In this paper, we investigated the fracture morphology, mechanical properties and acoustic emission characteristics of rock masses with different fracture patterns and different grain size compositions under compression shear conditions. In this study, rock like specimens contacting four opening flaws were subjected to triaxial compression tests to investigate the effects of flaws’ inclination angle on compressive strength and cracking behavior in rock masses under different confining pressure. Clarifying the principles of proportioning optimization for brittle transparent rock like specimens with differential fracture structures is crucial for the visualization study of the internal.

Six bi material configurations were tested under three point bending using pre notched beams, with variations in layer thickness and initial notch location. single material tests were also conducted to determine the uniaxial compressive strength, tensile strength, and fracture toughness of each constituent material. Numerical simulations reveal significant reductions in uniaxial compressive strength for protruded specimens compared to intact specimens, with eccentric protrusions showing more pronounced weakening than central protrusions. To investigate the variations of fracture geometric characteristics with normal stresses, a total of six fractured rock specimens, including cubic cement and cylindrical sandstone specimens with different grain sizes, were chosen to conduct the normal compression tests.
