A review of the response of sand under high strain rate (HSR) loading is presented. The response observed in HSR uniaxial compression tests, split-hopkinson pressure bar (SHPB) tests, and triaxial tests is investigated. Previous monotonic HSR tests have been reviewed, summarized, and combined in ord...
