Xuhai Tang
Professor at Wuhan University

Prof. Tang is the editorial board member of the “International Journal of Rock Mechanics and Mining Sciences”. His group developed the microscale Rock Mechanics Experiment (micro-RME) system and AiFrac-TOUGH software, in order to understand and control the rock fracturing with Hydraulic-Mechanical-Thermal coupling process. This micro-RME system, including nanoindentation and atomic force microscope, is able to investigate the mechanical property of rock-forming minerals and micro-cracking, which is especially useful to test the filling in fractures and arbitrarily-shaped meteorites. Meanwhile, this AiFrac-TOUGH software is able to simulate three-dimensional fracturing at multiscale, such as fracking in field work. His achievement contributes to the smarter unconventional petroleum production, thermal energy exploitation and future space mining.
