dc.description.abstractThe authors deserve praise for gathering together many different strands of evidence that clarify the mechanics of pile penetration in sand. In their review of numerical approaches to the problem, they correctly indicate, citing work by Arroyo et al. (2011), that simulations based on the discrete-element method (DEM) have offered quantitative agreement with measurements of tip resistance in calibration chambers. They go on to note that “DEM analyses of the surrounding stress field remains limited by the number of particles that can be considered.” The purpose of this discussion is to show that such limitation of DEM models is not as strong an impediment to obtaining meaningful stress fields as the authors may have feared. Butlanska et al. (2014) performed DEM analysis of a cone penetration test (CPT) in a virtual calibration chamber (VCC). Their analysis was performed at three scales, i.e., macroscale, mesoscale, and microscale. Some of the results they presented are subsequently reanalyzed and extended.
