Abstract
In the study of soil behavior under extreme loading such as blasting, it is necessary to take into account the effect of strain rate on soil behavior. The stain rate is of overriding importance in such study, where the load is expected to act as a single pulse and stress produced by the blast pressure increases so rapidly that the material behaves significantly different from that under quasi-static loadings. The modeling and experimentation of high strain rate phenomena are very important in determining the behavior of soils under critical events. It is widely accepted in the solid mechanics community that the strength, constitutive behavior, and overall response of soils are highly dependent on the strain rate. The dynamic properties of soils have been extensively investigated to predict the response of solids subjected to blasts, earthquakes, pile driving, meteor impact and many other transient loads. Despite existing studies, the behavior of soils at high strain rates and under various confining pressures, saturation, particle distribution, void ratios and other pertinent conditions have yet to be fully characterized.
