Thermo-mechanical degradation and crack evolution of granite subjected to liquid nitrogen cooling cycles for thermal reservoir stimulation

Liquid nitrogen (LN2)-assisted fracturing has emerged as a promising technique to enhance the productivity of hot dry rock (HDR) geothermal reservoirs. To elucidate the progressive mechanical degradation and fracture mechanisms of granite under cyclic thermal shocks, this study integrates ultrasonic...
