The effect of low density polyurethane foam on the axial crushing of thin-walled (D/t > 600) circular metal tubes is studied under quasi-static and dynamic loading conditions. The mode of deformation of the tube is found to change from irregular diamond crumpling to axisymmetric bellows folding due
