Abstract EN
Flaws and discontinuities play a crucial role in the failure process of rocks.
To investigate the fracturing mechanism of rock with combined flaws composed of crack and hole, the digital image correlation (DIC) method is used to record and analyze the rock failure behavior.
Coupled static and dynamic loads are applied on granite specimens with prefabricated flaws by a modified split Hopkinson pressure bar (SHPB) device.
The dynamic mechanical properties of the granite specimens are affected by the flaw inclinations with the loading directions.
With the inclination angle increasing, the combined strength and peak strain both decrease first and then increase.
Full- and local-field strain evolution of the granite specimens is analyzed in a quantitative way by using DIC technique.
The specimens with a flaw angle of 45° are broken relatively evenly with homogenous small particle sizes.
The variation trend of fragment sizes is consistent with that of combined strength and absorption energy of the specimens.
