WitrynaOne-dimensional compressive stress-strain curves with the strain rates ranging from 460 to 1300 s −1 were obtained under different compactness levels. Combining with the static compressive results (strain rate of 10 −4 s −1 ), it is found that coral sand is affect with strain rate obviously. Witryna1 mar 2014 · The dynamic compressive behavior of sorted and unsorted Eglin sand (Quikrete #1961 sand quarried in Pensacola, FL) under confinement was characterized under dry or moisture conditions at strain rates near 600 s−1 using a long split Hopkinson pressure bar, respectively.

Witryna1 cze 2024 · It can be observed that the stress–strain response of partially saturated sand generally stiffens with increasing initial dry density prior to water lock-up, while stiffening decreases with increasing saturation. An increase in confinement rigidity causes a rise in stiffness with lock-up occurring only in specimens confined in steel … cursor stopped working in documentWitryna22 paź 2024 · In this paper, a split Hopkinson pressure bar (SHPB) apparatus is used to conduct impact tests on two types of coral sand to investigate mechanical behavior.
