    Analysis on characteristics and mechanism for rock fracture in deep rock with cracks under dynamic-static coupling effect by Jinjin Ge, Yongqi Jia, Wei Huang, Meilu Yu, Suqian Ni, Ying Xu, Leilei Yu, Keke Gu

    Published 2024-12-01
    “…The study revealed three key findings: (1)The dynamic compressive strength of specimens with pre-existing cracks exhibited a non-monotonic relationship with crack inclination angle under uniaxial stress, contrasting with an increasing trend under confining pressure, highlighting the significant effects of confining pressure and strain rate. (2)Confining pressure significantly altered the failure modes, with specimens failing predominantly in axial tension at 0° and 90° crack inclinations, and a mix of axial tension and shear at 30° and 60°, indicating complex failure mechanisms. (3)The pre-existing crack angle under confining pressure influenced the propagation path and fractal dimension of the specimen, with an increasing angle correlating to higher fractal dimensions and a positive impact on compression peak stress. …”
