“…The entrance of the elliptical conical column wall into foam filler results in shorter fold lengths and increases the number of fold formed. Santosa et al stated that the encroachment of the column wall into the aluminum foam filler allows an additional compression in the foam and retards the sectional collapse of the column [9], [10]. A similar filler elliptical conical encroachment effect is also seen on the surface images of partially crushed foam-filled tubes fillers and tubes in Fig.…”

“…The base and upper plates were modeled using an elastic-plastic solid element model called material Type 1. This material model corresponds to elastic-plastic behavior with isotropic hardening and elastic-plastic behavior can be introduced by specifying the yield stress and tangent modulus or specifying the effective plastic strains and stresses [10].…”

“…Extruded structural aluminum elliptical hollow sections have recently been introduced to the vehicle of aerospace, automotive and marine construction sector [1]- [10]. These structural elements can offer greater structural efficiency than circular hollow sections when subjected to bending or combined loading, or when used as columns with intermediate restraint about the weaker axis, since they possess different major and minor axis flexural properties [3].…”

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.

“…Santosa and Wierzbicki [7] investigated the crushing behavior of aluminum honeycomb and foam-filled box columns numerically and experimentally and showed that the effect of filler on the tube crushing load was similar when the strong axis of the honeycomb was through and normal to the compression axis, proving that both axial and lateral strengths of the filler were effective in increasing the crushing load of the tube. Further, Santosa et al [8] noted that the bonding between filler and tube wall increased the average crushing load of filled tube over the unbounded filled tube when appropriate tube geometry and foam density were chosen. Aktay et al [9] investigated the quasi-static crushing of extruded polystyrene foam-filled aluminum thinwalled tubes.…”

Modeling the progressive axial crushing of foam-filled aluminum tubes using smooth particle hydrodynamics and coupled finite element model/smooth particle hydrodynamics

et al. 2008

As alternatives to the classical finite element model (FEM), a meshless smooth particle hydrodynamics (SPH) method, in which the discrete particles represent a solid domain, and a coupled FEM/SPH modeling technique were investigated for the numerical simulation of the quasi-static axial crushing of polystyrene foam-filled aluminum thin-walled aluminum tubes. The results of numerical simulations, load-deformation histories, fold lengths and specific absorbed energies, were found to show satisfactory correlations with those of experiments and FEM. The results further proved the capabilities of the SPH Method and coupled FEM/SPH modeling technique in predicting the crushing behavior of foam-filled thin-walled tubes.
