Experimental and Numerical Investigations on Feasibility and Validity of Prismatic Rock Specimen in SHPB

Figure 13

Typical NMRI photos of cylindrical and prismatic marble specimen in three loading direction parallel sections: (a) cylindrical specimen and (b) prismatic specimen (note: the white part of the photo means that water is detected by NMRI and this region represents damage or failure occurring inside of the specimen; impact loading direction of the specimen: from right to left).
