Abstract
Expanded Polystyrene (EPS) geofoam has become a widely used material in geotechnical construction due to some of its advantageous attributes (such as very low unit weight, high strength to weight ratio and environmental friendliness) over traditional geotechnical materials. Nevertheless, the potential of EPS geofoam as an engineering material in geotechnical applications has not been fully explored. This paper presents a finite element simulation of a plastic hardening model developed to predict the mechanical behaviour of EPS geofoam based on the Drucker Prager yield criterion. Explicit integration is used to implement the finite element formulation in ABAQUS/Explicit. The model is verified using a set of experimental data available from a series of triaxial tests carried out on a variety of EPS geofoam manufactured in Australia.
