Determination of mechanical properties and full-field strain measurements of rock material under dynamic loads

We present a detailed experimental procedure for the quantitative determination of mechanical properties and full-field strain measurement of rock material under dynamic loads. Three kinds of testing methods, i.e., notched semi-circular bending, Brazilian disc, and uniaxial compression, were conducted using a split Hopkinson pressure bar (SHPB) system. Experimental setup, data acquisition and interpretation were described in detail. The digital...
