Cracking Evolution and Failure Characteristics of Longmaxi Shale Under Uniaxial Compression Using Real-Time Computed Tomography Scanning

To determine the cracking and failure characteristics of Longmaxi shale in deformation and failure under loading, cylindrical specimens were prepared to conduct a series of uniaxial compression tests. Real-time computed tomography (CT) at different stress levels were used to obtain reconstructed stereograms, and horizontal CT images and vertical slices were obtained for analysis. Based on the CT images and slices, the cracking evolution of...
