    Quasi-Static Axial Crushing of Extruded Polystyrene Foam-Filled Thin-Walled Aluminum Tubes: Experimental and Numerical Analysis
    (Elsevier Ltd., 2006) Aktay, Levent; Toksoy, Ahmet Kaan; Güden, Mustafa
    The experimental and numerical quasi-static crushing responses of extruded closed cell polystyrene foam-filled thin-walled aluminum tubes were investigated. The numerical crash analysis of empty and foam-filled tubes was performed using the explicit finite element code PAM-CRASH™. Satisfactory agreements were generally achieved between the finite element model and experimental deformed shapes, load–displacements, fold lengths and specific energy absorptions. The model and experiments have also highlighted the several effects of foam filling on the crushing of thin-walled tubes. The energy absorptions in foam-filled tubes were further shown to be higher than the sum of the energy absorptions of empty tube (alone) and filler (alone).

    Modeling the Progressive Axial Crushing of Foam-Filled Aluminum Tubes Using Smooth Particle Hydrodynamics and Coupled Finite Element Model/Smooth Particle Hydrodynamics
    (Elsevier Ltd., 2008) Aktay, Levent; Johnson, Alastair F.; Toksoy, Ahmet Kaan; Kröplin, Bernd Helmut; Güden, Mustafa
    As alternatives to the classical finite element model (FEM), a meshless smooth particle hydrodynamics (SPH) method, in which the discrete particles represent a solid domain, and a coupled FEM/SPH modeling technique were investigated for the numerical simulation of the quasi-static axial crushing of polystyrene foam-filled aluminum thin-walled aluminum tubes. The results of numerical simulations, load-deformation histories, fold lengths and specific absorbed energies, were found to show satisfactory correlations with those of experiments and FEM. The results further proved the capabilities of the SPH Method and coupled FEM/SPH modeling technique in predicting the crushing behavior of foam-filled thin-walled tubes.
