Experimental investigation on damage characteristics and fracture behaviors of granite after high temperature exposure under different strain rates

Rock mass engineering in a high-temperature environment is often affected by complex stress conditions. In this paper, to reveal the damage characteristics and fracture behaviors of granite after high temperature exposure under different strain rates, twenty-four uniaxial compression tests were carried out on granite specimens under the combined action of six temperatures (25 °C, 200 °C, 400 °C, 600 °C, 800 °C, and 1000 °C) and four quasi-static...
