    Experimental and simulation study on tensile mechanical characteristics and crack development law of sandstone after thermal treatment by Jing Yang, Sheng-Qi Yang, Guang-Jian Liu, Bo-Wen Sun, Wen-Ling Tian, Jin-Zhou Tang

    Published 2025-03-01
    “…Based on scanning electron microscopy (SEM), X-ray diffraction (XRD) tests, it is determined that the thermal cracks in the rock show the characteristics of ''disorderly distribution, centralized development, a large number of microcracks develop to form penetration trend, and local penetration to form complex crack network''. By using image threshold segmentation to quantitatively analyze the high temperature thermal damage, it is determined that the high temperature thermal damage presents the characteristics of ''slow increase, rapid increase''. …”
