... orientations of 30°, 60°, and 90° with respect to the horizontal. Results indicated different peak strengths at failure with highest and lowest values for the 90° and 30°-specimens, respectively. Failure occurred at different mean effective stresses with different magnitudes of pore water pressure built up...

... ABSTRACT: The magnitude and orientation of the in-situ stresses are greatly impacted in areas where the ground elevation changes dramatically within the field boundaries. The stress model for XGS field, located in onshore China, is constrained using a comprehensive workflow starting from...

The mechanical properties of the bulk rock are obtained by two-step Mori-Tanaka homogenization. This model captures the propagation...

... known that these features act as weakness planes in the rock matrix and thus studying the mechanical behavior of shale should incorporate the influence of bedding planes. Numerous investigations have been conducted so far to understand the influence of bedding plane orientation on the deformation...
