Numerical simulation of fracture propagation of heterogeneous rock material based on digital image processing

For the Three Gorges granite,a finite difference software package FLAC is used to study failure process of heterogeneous rock material.Firstly,proper scale of finite difference grids is under consideration with scanning electron microscopy photo of the granite.Based on mineral components identification results of the granite and fuzzy clustering method,the actual image data are transformed into the finite difference grid by applying image...
