    Abstract:
    This document presents the results from discrete element method (DEM) simulations of interface shear compared to previously published data from similar physical experiments. Rough shafts emplaced in granular assemblies are subjected to monotonic and cyclic loading and the results evaluated. The granular‐continuum interface behavior for different anchor surface roughnesses is...

    Abstract:
    Soil‐structure interaction has been an area of active research since the 19th century and has evolved significantly over the past 150 years (Kausel, 2010). Previous soil‐structure interaction studies have been based on numerical simulations (e.g., Costantino et al. 1976; Jensen et al. 1999; Jensen, Edil et al. 2001; Jensen, Plesha...
