Impact compressive response of dry sand
Witryna26 mar 2010 · Fractured sand is shown to exhibit abrasion, attrition and fracture modes with visual self-similarity limited to specific particle size range roughly divided into classes larger or smaller than ~50 microns. Initial particulate media density affects the bulk response to high-pressure/rate events. Witryna1 mar 2008 · OSTI.GOV Journal Article: Impact Compressive Response of Dry Sand..
