Characterization and modelling of expanded polystyrene structures

Expanded polystyrene is one of most commonly used materials for packaging of sensitive products that must arrive undamaged from the production line to the costumer. Although its wide use the expanded polystyrene is a complex material showing nonlinear characteristics in relation to strain and strain rate. The purpose of thesis is to study the characteristics of expanded polystyrene of given density and implement them into numerical model. Further the modelling of expanded polystyrene structure’s response under static and impact loading is expected with nonlinear static and explicit transient analysis, respectively. The actual experiments of static and impact loading of expanded polystyrene should also be performed and compared to the numerical results.
