Temperature-induced rock failure occurs in geothermal exploitation, nuclear disposal, and other underground engineering scenarios. In this paper, the conventional spherical discontinuous deformation analysis (SDDA) method is extended to simulate the temperature-induced rock failure problems. Firstly...
