To understand the response of calcareous sand at HSRs, a series of dynamic tests is performed using the split Hopkinson pressure bar(SHPB) with steel sleeve, including 6 validation tests of bar-against-bar and 16 comparative tests relevant to the relative density and strain rate of calcareous ...
Due to the inherent properties of calcareous sand, the dynamic behavior of cemented calcareous sand (CCS) would differ from that of cemented silicon sand. In this study, a series of split Hopkinson pressure bar (SHPB) tests were conducted to investigate the effect of particle size and particle...
