...S.-S. Yeo; Y.G. Hsuan ABSTRACT: The short- and the long-term compressive behavior of an expanded polystyrene (EPS) geofoam were both evaluated to assess the effects of temperature and stress. The short-term compressive strength decreased bi-linearly as temperature increased with a transition point...

... that the compressive strength decreases linearly with inclined angle, whereas the compressive strain increases. The long-term compressive behavior (i.e. creep) was evaluated using the stepped isothermal method (SIM) at applied stresses of 10%, 20% and 30% of the normal compressive strength. The creep strain increases...
