Abstract: This study explores the link between the monotonic and cyclic undrained behaviour of sands using the discrete element method (DEM). It is shown that DEM can effectively capture the flow deformation of sands sheared under… read more here.

DOI: 10.1016/j.jnnfm.2019.02.009
Abstract: Abstract The onset of flow in vibrated layer of viscoplastic fluid is investigated theoretically, using a lubrication approximation. The rheological behavior of the fluid is described by the Herschel–Bulkley model. The equation describing the evolution… read more here.
