Impact compressive response of dry sand
Witryna22 paź 2024 · In this paper, a split Hopkinson pressure bar (SHPB) apparatus is used to conduct impact tests on two types of coral sand to investigate mechanical behavior. Using this approach, compressive stress-strain curves of the one-dimensional strain state are obtained, with strain rates ranging from 460 s −1 to 980 s −1.
