An experimental approach for determination of the Weibull homogeneity index of rock or rock-like materials

The spatial variation of the physical–mechanical properties of rock or rock-like materials is an intrinsic characteristic of the materials induced by multiscale material heterogeneities. The Weibull distribution is a widely used statistical model for the characterization of non-uniform mechanical property distribution of rock or rock-like materials at particle scale. The key parameter of the Weibull distribution is the homogeneity index, m. In...
