Abstract

A split Hopkinson pressure bar (SHPB) was used to investigate the dynamic response of soil under compression in the range of strain rates from 466 to 1096^s-1 and at room temperature. Quasi-static compressive properties of soil were investigated by a MTS30-2.0 materials test system. The compressive strength of the soil specimens showed positive strain-rate sensitivity in the range of strain rates. A slight influence of soil microstructure was observed. This residual strength of the damaged/fragmented soil was remained. In some cases, the strength was larger than the quasi-static compression strength of soil. The results were important to be used in modeling soil impacts.
