Prediction of Mechanical Properties of Igneous Rocks Under Combined Compression and Shear Loading Through Statistical Analysis

Mechanical responses of rocks to combined compression and shear have attracted increasing attention but still lack comprehensive understanding. Sixty-eight laboratory tests are conducted on basalt and granite specimens sourced from different origins to generalize the effects of specimen inclination on the mechanical properties of igneous rocks. A novel regression model is established to predict peak strength and elastic moduli of igneous...
