Shear Strength of Sands During Rapid Loadings

Abstract

Triaxial tests with times-to-failure ranging from 5 min to 5 msec were used to investigate effect of strain-rate on strength of dry and saturated sands; new techniques were developed for applying strains rapidly, and for measuring resultant stresses and pore pressures; peak friction angles of sands tested were substantially independent of failure-time; however, excess pore pressures generated within saturated loose sands did vary with failure-time.
