dc.description.abstractThe discrete element method (DEM) is progressively gaining acceptance as a modelling tool for engineering problems of direct geotechnical relevance. One area for which the method seems naturally well adapted is that of crushable soils. Grain Crushing is generally modeled using the discrete element method (DEM) via two alternative methods: replacing the breaking grains with new, smaller fragments; or by using agglomerates. The latter, despite being very helpful for the understanding of the micromechanics occurring in a single grain, becomes an unpractical tool for the modeling of larger scale problems. In fact, when considering those alternatives there is always a need to balance computational expediency, accuracy of results and soundness of principle. This work focuses on the encounter of those two last requirements, as exemplified in a series of simulation of high pressure one-dimensional and isotropic compression of Fontainebleau sand. A recently developed model for crushable soils is briefly outlined. It is shown that the upscaling procedure adopted allows a considerable reduction of computational bargain without losing accuracy in terms of grain size distribution evolution and mechanical response.
