Peridynamic simulation of fracture mechanical behaviour of granite specimen under real-time temperature and post-temperature treatments

This study developed a fully coupled thermo-mechanical model within the framework of ordinary state-based peridynamics to investigate the thermal-mechanical properties and fracture characteristics of granite materials under real-time temperature (RT) and post-temperature (PT) treatments. Moreover, a modified multi-layer computational method was proposed to eliminate the effect of thermal gradient-induced cracks. In this method, the size of the...
