Cracking mechanisms of a medium-grained granite under mixed-mode I-II loading illuminated by acoustic emission

Cracks at various scales in rock masses are often subjected to mixed-mode I-II loadings in Earth's dynamic processes and geotechnical engineering works. Insightful understanding of the macroscopic and microscopic cracking mechanisms of rocks under this loading condition is of far-reaching significance. To investigate the effect of the loading condition and granite heterogeneity on the cracking mechanism, we conduct three-point bending tests on...
