The experimental results of shale from Lower Silurian longmaxi formation subjected to uniaxial compression
There are experimental results of longmaxi formation shale subjected to uniaxial compression, including the stress-strain curves, macroscopic mechanical parameters and failure modes. The shale samples were divided into four groups in terms of layer orientations, which were predefined as 0°, 30°, 60°, and 90°. Every group contains three samples. Cylindrical samples with diameters of 50 mm and lengths of 100 mm were cored from shale, with the parallelism and smoothness of end surfaces meeting the suggested experimental standards of International Society for Rock Mechanics (ISRM). All the uniaxial compression experiments were conducted by strain controlling mode at a constant strain rate of 0.001%/s.
