“…Parametric investigations of the effects of the length of the tube, the thickness and type of braid, and the loading conditions on the crushing behavior of the tubes have been examined. Hage et al [5] developed a finite element model based on modified Chang-Chang failure criteria to elucidate the quasi-static axial crush behavior of square aluminum-composite hybrid tubes. They also explored the effects of adhesion, friction between the aluminum tubes overwrapping with composite and verified their numerical model using experimental data.…”

“…As a result, several researchers have recently addressed metal tubes that wrapped with a fiber-reinforced plastic composite. Various experimental and theoretical studies of the behaviors of different material and hybrid tubes have been carried out [1][2][3][4][5][6][7][8][9][10][11][12][13]. The theoretical model developed by Alexander [1] for calculating the average crushing force of a cylindrical tube under static axial crush is well known.…”

The commercial finite element program LS-DYNA was employed to evaluate the response and energy absorbing capacity of cylindrical metal tubes that are externally wrapped with composite. The numerical simulation elucidated the crushing behaviors of these tubes under both quasi-static compression and axial dynamic impact loading. The effects of composite wall thickness, loading conditions and fiber ply orientation were examined. The stress-strain curves under different strain rates were used to determine the dynamic impact of strain rate effects on the metal. The results were compared with those of a simplified analytical model and the mean crushing force thus predicted agreed closely with the numerical simulations. The numerical results demonstrate that a wrapped composite can be utilized effectively to enhance the crushing characteristics and energy absorbing capacity of the tubes. Increasing the thickness of the composite increases the mean force and the specific energy absorption under both static and dynamic crushing. The ply pattern affects the energy absorption capacity and the failure mode of the metal tube and the composite material property is also significant in determining energy absorption efficiency.

“…The measurement of this kind of displacement field is significant to evaluation of the deformation modes and understanding of the deflection mechanisms of the structures. For instance, when a thin-wall tube is subjected to axially quasi-static or impact load, large out-ofplane displacement will appear in the normal direction to the tube surface, which offers various buckling modes of the tubes with progressive axial folding [1,2]. In recent years, these structures have attracted increasingly more attention in the design of transportation systems due to their effective capability to absorb kinetic energy during the performance of plastic buckling, to meet increasing demands for using lighter and low-cost aluminum alloy structures in the systems for energy saving and crushing protection [3][4][5].…”

Measurement of out-of-plane deformation is significant to understanding of the deflection mechanisms of the plate and tube structures. In this study, a new surface contouring technique with color structured light is applied to measure the out-of-plane deformation of structures with one-shot projection. Through color fringe recognizing, decoding and triangulation processing for the captured images corresponding to each deformation state, the feasibility of the method is testified by the measurement of elastic deflections of a flexible square plate, showing good agreement with those from the calibrated displacement driver. The plastic deformation of two alloy aluminum rectangular tubes is measured to show the technique application to surface topographic evaluation of the buckling structures with large displacements.

“…The experimental results demonstrated that the new metal rubber isolator is able to isolate vibration with a favorable vertical capacity and horizontal restorability. Guillow et al [4] and ElHage et al [5] studied the static axial compression mechanical behavior of thinwalled circular aluminum tubes. Yuan et al [6] analyzed the inflation mechanism examined for a composite cylindrical tube composed of two incompressible rubber materials, where the inner surface of the tube was subjected to suddenly applied radial pressure.…”

The impact response of rubber and foam aluminum cushion spacers is simulated by ABAQUS finite element analysis software. It indicates that shape designed structures of rubber and foam aluminum buffer effectively in impact conditions. The rubber structure induces different deformation modes of the cushion spacer during the impact process and the deformation mode can be controlled. Elastic deformation of the rubber structure can accumulate energy. Rubber cushion endergonic and exergonic processes are reversible. It transforms kinetic energy into potential energy, prolongs loading time and releases the impact loading peak. Plastic deformation of foam aluminum can absorb energy and dissipation impacts kinetic energy. The process of aluminum dissipation energy is irreversible. Foam aluminum plastic dissipation energy is analyzed by a simplified mechanical theory. And corresponding impact experiments verify that the structured design rubber cushion spacer is valid.
