Abstract
Expanded Polystyrene (EPS) geofoam has potential benefits in construction industry for its desirable mechanical properties such as extremely light weight and volume contraction under compressive loading. However, the engineering properties and applications of this material are yet to be fully explored. In this paper, a finite element formulation is presented for a plastic hardening model developed for EPS geofoam. Formulation of the model is based on the Drucker Prager yield criterion but additional parameters are used to simulate the hardening behaviour of the geofoam. The finite element model is verified using experimental data from a series of triaxial tests carried out on a variety of EPS geofoam manufactured in Australia.
