Crack damage evolution of shale is crucial to the hydraulic fracturing treatment and engineering stability. Although many effects have been done on the macroscopic characteristics of shale, yet the microscopic failure mechanism is not well understood. A uniaxial compressive test on black shale was conducted under topographic monitoring using in situ X-ray micro-tomography (µCT). A series of high-resolution reconstruction images were obtained by carrying out CT scans at six key points throughout… CONTINUE READING
