  • DEM modelling to assess internal stability of gap

    It is believed that the relative density (D r) can affect the internal stability of the gap-graded soils and hence the erosion of their fine particles (i.e. susceptibility to suffusion).This paper investigates the influence of D r on the contribution of fine particles to soil fabric. A new procedure is proposed to produce samples with target D r using the discrete element method (DEM).

    2020-6-4  Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity for liquids is nearly always measured with respect to water at its densest (at 4 °C or 39.2 °F); for gases, air at room temperature (20 °C or 68 °F) is the reference. The term "relative density" is often preferred in ...
