High strain rate stress-strain response of soils - A review

Abstract

In the current study, a review on the response of soils subjected to high strain rate loading is presented. High strain rate loading on soil may be applied through high loading rate uniaxial compression tests, triaxial tests, split Hopkinson pressure bar (SHPB) tests, and shock tube test. Herein, the results of SHPB tests from the literature have been reviewed and the effect of strain rate on the stress-strain response of soils, elastic modulus, initial inertia, peak and failure stresses of soils have been studied. The effects of strain rate, initial void ratio, confining pressure and saturation on the high strain rate response of soils are also discussed. The review thus provides complete understanding of soil behavior under high loading rates.
