Fractal Study for Micro-Crack of Mud-Shale
2016
The structure, distribution and evolution of micro-crack within the mud-shale are studied in this paper. The micro-fracture behavior of mud-shale has fractal characteristics. Fractal method is used to quantitative description of the damage evolution behavior of the mud-shale. The study shows that the variation of the fractal dimension in the domain of the bearing surface can reflect the internal damage evolution trend of the mud-shale. The fractal dimension has a nonlinear relationship with the applied stress.
