Study of shear resistance and anisotropy of layered shales
figure
posted on 2024-09-09, 09:15 authored by Min Gao, Bin GongBin Gong, Zhengzhao Liang, Shanpo Jia, Xianhui FengCharacterizing anisotropy remains challenging in rock mechanics. Particularly, the strengths and failure patterns of layered shales under shear load are significantly anisotropic mainly because of the bedding planes. Meanwhile, understanding the creation and propagation of shear fractures is critical for drilling, mining, tunnelling, exploitation of shale gas, etc. In this study, the shear resistance of layered shales is comprehensively investigated based on the direct shear tests numerically.
