“…It was concluded in the same study that the thin-walled foam-filled members could be used as efficient crash energy absorbers. Seitzberger et al [7,8] investigated the axial crushing of foam-filled square, hexagonal, octagonal and bitubular steel tubes. It was reported that considerable improvements with respect to energy absorption were obtained with foam filling particularly in bitubular configurations.…”

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.

“…But it would appear that no previous investigation has been made in the literature to study the crushing behavior of thin-walled elliptical cones with and without polymeric foam filling. Studies on energy absorption capability as well as the load carrying capacity of thin-walled extruded aluminum elliptical tubes and cones are however still scarce [8]. This was one of the motivating factors behind this paper.…”

Abstract-Present paper studies crush simulation of elliptical conical unfilled and foam filled subjected to compressive loading is studied in detail. The finite element analysis package PAM-CRASH 2G version 2005 was compared with existing results from experimental analysis has been done by previous investigation to ensure that the numerical analysis is sufficiently accuracies. The thin-walled extruded aluminum alloy and polymeric foam material offers vast potential for optimally tailoring a design to meet crashworthiness performance requirements. The energy absorption performance of thin-walled extruded 2024-T4 alloy and polymeric foam with variable cross-section in term of vertex angle and wall-thickness are numerically studied. From the results data that achieved from numerical analysis, the load versus deformation curves and analysis dynamic energy absorption versus deformation were plotted and calculated using MathWorks MATLAB Simulink commercial software's package version R2010a. Results showed that the tube's energy absorption capability was affected significantly by varying of velocity-impact and wall-thickness as well as vertex angle of conical cross-section. It is also found that as the filling polymeric foam into thin-walled tube increases the amount of absorbed energy than the empty tubes.Index Terms-Finite element modeling, elliptical conical, axial loading, energy absorption, foam filled.

“…Numerous of researches have been performed to investigate crush and energy absorption response of foamfilled thin-walled tubes under axial loading. Examples include foam-filled circular tubes (Borvik et al [1]; Kavi et al [2]; Toksoy and Guden [3]; Yan et al [4]), foamfilled square tubes (Hanssen et al [5]; Santosa et al [6]; Seitzberger et al [7]; Zarei and Kroger [8]), foam-filled conical tubes (Gupta and Velmurugan [9], Ahmad [10]), foam-filled tapered rectangular tubes (Mirfendereski et al [13]; Reid et al [14]), and foam-filled hat sections (Chen [15]; Song et al [16]). …”

Abstract:In this paper, sandwich tube components which consist of thin-walled circular tubes with aluminium foam core are proposed as energy absorption systems. The sandwich tubes were laterally crushed under quasi-static loading conditions. The sandwich tubes were crushed under two types of indenters and exposed to three different types of external constraints. The collapsing behaviour and the energy absorption responses of these systems were investigated by nonlinear finite element analysis through ANSYS-LS-DYNA. Various indicators which describe the effectiveness of energy absorbing systems were used as a marker to compare the various systems. It was found that the sandwich tube systems compressed by cylindrical indenters particularly the unconstrained system (STCIU) and the system with inclined constraints (STCIIC) offered a very desirable force-deflection in which the force is almost constant in the post collapse stage. The employing of external constraints was noticed as a feasible method of increasing the SEA particularly when cylindrical indenter is used.
