The combined scaled boundary finite-discrete element method: grain breakage modelling in cohesion-less granular media
journal contribution
posted on 2023-05-19, 03:57 authored by Luo, T, Ooi, ET, Andrew ChanAndrew Chan, Fu, SJA computational technique combining the scaled boundary finite element method (SBFEM) and the discrete element method (DEM) is developed. Both methodologies work in tandem to model two mechanisms i.e. grain-to-grain interaction via DEM; and breakage of individual grains via SBFEM. Both play important roles in characterising the response of granular soils. The combination of the two methods results in some advantages in computational flexibility and implementation in modelling grain breakage in granular materials. Parametric studies demonstrate the method’s ability to reproduce stress-strain curves in bi-axial tests of granular rock-fills; and qualitatively predicts characteristics of grain breakage observed in laboratory tests.
