... et al ., 1997; Cheng, 1998). In line with the loading decomposition scheme proposed by Abousleiman and Cui (1998), this unsaturated poroelastic problem could be decomposed into three separate resolved sub-problems to simplify the analysis, i.e. a poroelastic plane strain case (Case I), an elastic uni...

... at the rock surface by applying cryogenic fluid can cause strong local tensile stress and initiate fractures. We developed a laboratory system for cryogenic fracturing under true triaxial loading, with a liquid nitrogen delivery/control and measurement system. The loading system simulates confining stresses...
