Prediction of Mechanical Properties of Igneous Rocks

2019-8-27 · It is commonly recognized that rock failure results from the initiation and propagation of microcracks randomly distributed in the rock (Bieniawski 1967a). The external shear stress component facilitates the sliding between microcrack surfaces, leading to earlier microcrack initiation (McClintock and Walsh 1963 ; Hoek and Bieniawski 1965 ).
