Static and dynamic axial crushing of foam-filled sheet metal tubes

Quasi-Static Crushing and Energy Absorption Characteristics of Thin-Walled Cylinders with Geometric Discontinuities of Various Aspect Ratios

“…They also reported that the effect of strain rate and strain hardening effects of collapse behavior of thin-walled tubes are limited. Additionally, the geometric discontinuities such as cutouts and stiffeners in real time scenarios leads to stress concentration adjacent to the cut-outs that affects the crushing pattern of the structure (Reid et al, 1986). The axi-symmetrical fold pattern was observed in quasistatic loading during experimental scheme when cylindrical shells are subjected to various loading conditions (Dorin et al, 2017).…”

Quasi-static axial crushing of extruded polystyrene foam-filled thin-walled aluminum tubes: Experimental and numerical analysis

“…They also concluded that the simple addition of the uniaxial foam contribution gave the total average crushing load of filled tube. Guillow et al [6] have recently pointed out that the average crushing loads of polyurethane foam-filled aluminum (Al) thin-walled tubes were greater than the sum of the average crushing loads of empty tube (alone) and foam (alone), a result which contrasted with those of Reid et al [5] and Reddy and Wall [7]. Seitzberger et al [8] investigated the crushing behavior of Al closed-cell foam-filled monotubal and bitubal arrangements of square, hexagonal and orthogonal cross-sections and concluded that mass related average load level can be improved by filling tubular members with aluminum foam.…”

“…Lampinen and Jeryan [4] investigated the crushing of sheet metal tubes filled with low density polyurethane foams and concluded that foam filling stabilizes the deformation of thin-walled tubes. The crushing behavior of polyurethane foam-filled thin-walled metal tubes was also investigated by Reid et al [5], at quasi-static and dynamic deformation rates. It was concluded that tube wall interacts with the foam filler deformation resulting in a more tendency for the axisymmetric mode of deformation.…”

“…In particular, the behavior of elliptical profiles in the post ultimate region has not yet been examined. Besides defining the unloading branch of the load-deformation curve [5], an accurate description of this region also allows the possibility of quantifying the ductility of the system. The aim of the present work is to develop a finite element model to predict the full load-deformation Manuscript received May 15, 2013; revised July 10, 2013.…”
