Abstract
A modified Split Hopkinson pressure bar (SHPB) was used to carry out dynamic and static combined loading on prefabricated granite samples. Meanwhile, digital image correlation (DIC) technology was used to evaluate the failure mode of samples with different cylinder hole sizes under different loading conditions. In addition, the dynamic failure characteristics of different circular tunnel radii were obtained by numerical simulation software under...
