Impact compressive response of dry sand
WitrynaThe sands varied in grading and angularity, though at a strain rate of 103s−1the results for all three sands indicated a reduction in stiffness in 20% saturated samples compared to the dry sand, followed by a stiffening response for saturations of 40−100%, with the onset of lock-up behaviour varying between sands. Witryna1 sty 2007 · The strain rate effects on the compressive response of the sand were determined. The sand was also prepared to specimens with a higher initial density of 1.62×103kg/m3 for dynamic...

Witryna1 lis 2012 · In a uniaxial test a sample of sand is compressed axially while lateral strains are prohibited. There are three main mechanisms governing response of sand in uniaxial compression: (1) elastic compression of individual sand grains; (2) slippage and rearrangement of grains; (3) grain crushing. Witryna31 paź 2024 · As compared with dry soils, water plays more significant role, for load-bearing capability than the sand grains. The soil with lower clay/sand ratios has stiffened the mechanical properties under water saturated state, and pure clay and pure sand have reduced mechanical properties. 15.4 Conclusions
