Abstract:The axial crushing behavior of empty and Al close-cell foam-filled Al multi-tube designs (hexagonal and square) and E-glass woven fabric polyester composite and Al hybrid tubes were investigated through quasi-static compression testing. The effects of foam filling on the deformation mode and the crushing and average crushing loads of single tubes and multi-tube designs were determined. Although foam filling increased the energy absorption in single Al tube and multi-tube designs, it was not effective in increa… Show more
