Afrl-rw-eg-tp-2008-7405 Moisture Effects on the High Strain-rate Behavior of Sand (preprint)

Abstract

The effects of moisture content on the high strain rate mechanical properties of fine grain sand were characterized with a split-Hopkinson pressure bar. A controlled loading pulse allowed the sample to acquire stress equilibrium and a constant strain-rate of 400 s. The sand specimen confined in a hardened steel tube, had a dry density of 1.50 g/cm with… (More)
