Quantification of the Dynamic Compressive Response of …

WitrynaUniaxial compressive behavior of Mason sand, a poorly-graded local sand supplied by Colorado Materials (Longmont, CO), was investigated on a long split Hopkinson pressure bar. Sand grains were confined inside a hardened steel tube and capped by tungs Witryna26 sie 2024 · In the field of soil drying methods, rapid microwave heating is progressively replacing conventional techniques. Due to the specific heat transport caused by microwaves, the drying process can significantly modify soil structure, which, in turn, can influence mechanical and filtration characteristics. In this study, we compared … simple flourish line

Dynamic mechanical behavior of different coral sand subjected to impact ...

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 … WitrynaAbstract. Stress-strain curves from 61 uniaxial strain tests are presented which depict the response of three dry sands to intense transient pressures; the loadings ranged … 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. simple flourish
