“…A study on the bending collapse of thin-walled prismatic columns filled with Al foam and Al honeycomb further showed that columns filled with honeycomb and foam were more efficient in terms of specific absorbed energy (SAE) than the thickening of the column wall [2]. Børvik et al [3] noticed that during a crash event the crushing load was neither pure axial nor pure bending but rather a combination of two and conducted a series of axial and oblique quasi-static loading tests on the empty and Al foam-filled tubular columns. It was shown by the same authors that the peak load and energy absorption decreased strongly with increasing loading angle.…”

Finite element and coupled finite element/smooth particle hydrodynamics modeling of the quasi-static crushing of empty and foam-filled single, bitubular and constraint hexagonal- and square-packed aluminum tubes

The quasi-static axial crushing behavior of empty and Al and polystyrene foam-filled Al single, bitubular and multi-tube-packed (hexagonal and square packing) configurations were investigated experimentally and numerically. Tubes were modeled using finite element and coupled finite element/smooth particle hydrodynamics. The numerical specific absorbed energy (SAE) values, deformation patterns, load values and number of folds formed were found to show agreements with those of experiments. Among the tested tube configurations only hexagonal-and square-packed empty tube designs showed increased SAE values over that of single empty tube. Furthermore, foamfilled multi-tube designs both hexagonal-and square-packed designs were found energetically more efficient than Al foam-filled single tubes at similar foam filler densities. The increased SAE values of multi-tubes were attributed to the frictional forces of the multi-tube designs and constraining effect of the die walls accommodating the tubes.

“…The structural crashworthiness signifies an important mechanical property under impact loadings and it was found to vary significantly with changes to parameters such as laminate layer thickness and density [14]. By definition, the crashworthiness is the ability of a structure to absorb impact energy with minimal attenuation of survivable space.…”

This paper investigates the computational-based deformation and energy absorption capability of laminated metal panels composed of high-strength steel and aluminium alloy under low-velocity impact. Layering aluminium alloy plates with high-strength steel has become of interest for reducing the overall density of armoured vehicle bodies while improving the ballistic resistance. In order to enhance the attractiveness of laminated plate construction, it is essential to study the strength of the two different metals in a laminated panel under low-velocity impact before performing a ballistic impact. Two types of laminated panels were constructed: two-layer and three-layer configurations. Both were oriented transverse to the loading axis and solved using quasi-static analysis. The deformation behaviour of these panels was studied and the energy absorption capacities were quantified. The results showed that the energy absorption capacities of the laminated panels were on average 220% higher in the three-layer configuration panels compared to in the two-layer configuration panels. The deformation lengths in the three-layer configuration panels were on average 22% smaller than those of the two-layer configuration panels with 25% to 30% weight reduction. The best three-layer configuration panel will be used later for investigating a suitable combination panel for armoured vehicles subjected to ballistic impact.

“…In addition, the presence of the ller material in thin-walled tubes seems to improve crush stability and energy absorption capacity [4][5][6]. One of the earliest investigations on the crushing behavior of thin-walled sections lled with lightweight polyurethane foam (PU foam) was conducted by Lampinen and Jeryan [7].…”

Abstract. This paper deals with the dynamic response and energy absorption of foamlled aluminum parabolic tubes under axial impact loading. The numerical crush analysis of empty and foam-lled tubes is performed using non-linear nite element techniques. The e ects of geometrical (wall thickness) and material parameters (foam density and Young's relaxation modulus) on the impact response and energy absorption capacity of foam-lled tube are investigated using numerical models. The results show that the foam properties have signi cant e ect on the crushing behavior, force and impact acceleration magnitude, and energy absorption capacity. Furthermore, there is a critical foam density beyond which the structure loses its energy absorption performance. Experimental results acquired from a test setup are used for validating the Finite-Element Analysis (FEA). There is good agreement between numerical and experimental results.
