摘要：The article presents the results of numerical crush simulations of thin-walled structures with a square cross-sectionand partial flling with foamed material. The influence of the length of the flling on the values of the energy effciency index was analysed. Four types of foamed material were subjected to numerical analysis. The researchwas conducted using FEM in Abaqus 6.14 program. The obtained results were presented in the following forms:load-shortening characteristics, tables and diagrams. The best energy absorbing properties are shown by modelsflled with aluminium and polyethylene terephthalate foam.
