- The fundamental mechanisms of internal instability operate at the particle scale. The particle fabric determines susceptibility to internal instability and empirical criterial, such as those proposed by Kézdi (1979), quantify this fabric effect indirectly. Previous particle scale analyses were based on DEM simulations using spherical particles and highly simplified contact models. This study examines for the first time real sand samples with high resolution micro-computed tomography. The findings were presented and discussed at the 25th Meeting of the European Working Group on Internal Erosion as a first step towards their use to inform filter design and specifications.
