... and microcracks are potential sources of failure for rock materials because of stress concentration (Aadnoy & Angellolsen 1995, Bordia 1971, Zhang et al. 2014). When disturbed by dynamic loads from blasting, seismicity, or rockbursts, the underground rocks would be vulnerable to tensile failure...

..., Central South University, Changsha, Hunan, P.R. China ABSTRACT: The strength of rock materials is largely affected by water, and the static properties have been widely studied before, while there is virtually no data for dynamic com- pressive strength of saturated rock at different strain rates. In order...
