What Can Grading Entropy Tell Us About Soil Fabric?

Leak, James; Barreto, Daniel; Dimitriadi, Vasiliki

Abstract

These slides were presented at the 19th annual geomechanics form micro to macro conference at Imperial College London in 2022. They detail an investigation into characterising soil fabric effects using the normalised entropy coordinates proposed by Lőrincz (1986). It is suggested that the normalised coordinates are able to characterise the strong and weak fabric networks in soils. Using the major and minor components of the fabric tensor (in discrete element simulations), it is seen that the A-coordinate is associated with contacts aligning in the major principal fabric direction (i.e. the strong fabric network), whereas the B-coordinate is associated with contacts aligning in the minor principal fabric direction (i.e. weak fabric network).
