Axial crushing behaviour of the polyurethane foam-filled aluminum cylindrical tubes with shallow spherical caps (combined thin-walled structures) is studied both experimentally and numerically. Non-linear dynamic finite element analyses were carried out to simulate the quasi-static tests. Satisfactory agreements were generally achieved between the finite element model and experimental deformed shapes, load–displacements, fold lengths and specific energy absorptions. Influence of important parameters such as semi-apical angle, length of cylindrical and spherical caps, diameter and density of foam filler was discussed and the results highlight the advantages of using foam-filled shell of the combined geometry as energy absorber.
