Concrete-filled double skin structural members, comprising of two metal tubes and concrete infill between them, have been gaining popularity in engineering because their high strength, large stiffness, good ductility easy maintenance. The use aluminium these members can further enhance performance, as alloy offers lightweight corrosion resistance. This study presents experimental numerical inve...

Thin-walled tubular structures are widely used in industries such as automotive, aerospace and military because of their lightweight excellent performance under different loading conditions. This study aimed to investigate the lateral crushing square aluminium tubes filled with cores (honeycomb, polyurethane foam mixed these two fillers). Different failure modes tested have been observed they p...
