Quasi Static Compression

The energy absorption of different cell structures for closed-cell aluminum foam-filled Al tubes are investigated through quasi-static compression testing. Aluminum foams are fabricated under different pressures, obtaining aluminum foams with different cell sizes. It is found that the deformation of the foam core is close to the overall deformation, and the deformation band is seriously expanded when the cell size is fined, which leads to the increase of interaction. Results confirm that the foam-filled tubes absorb more energy due to the increase of interaction between the foam core and tube wall when the foaming pressure increases. The energy absorption efficiency of foam-filled tubes can reach a maximum value of 90% when the foam core is fabricated under 0.30 MPa, which demonstrates that aluminum foams fabricated under increased pressure give a new way for the applications of foam-filled tubes in the automotive industry.

The effect of low density filler material comprising polyurethane foam on the axial crushing resistance of Nomex honeycomb under quasi-static compression conditions was analyzed. Honeycombs with two different densities, two different heights and similar cell size, along with five different densities of polyurethane foams were used in the research. A total of 14 unfilled Nomex honeycombs, 15 polyurethane foams, and 39 foam-filled Nomex honeycombs were subjected to quasi-static compression loading. The crushing load and capability of foam-filled Nomex honeycomb structure in absorbing the energy were found to increase significantly since the cell walls of honeycomb were strengthened by the foam filler; the walls did not buckle at the very beginning of compression loading. The failure mechanism of the foam-filled honeycomb was analyzed and compared with the unfilled honeycomb.

This paper is aimed to investigate the crushing response of single square honeycomb panels under quasi-static compression loading. Two types of materials are used in this study, which refers to 100 % polylactic acid (PLA) and 70 % PLA filled 30 % carbon fibre (PLA/CF). Single honeycomb panels were fabricated through additive manufacturing technique, and assembled using slotting technique. The effect of boundary factor on the single square honeycomb panels have been studied, which refers to none, single-side, double-side boundary conditions. The effect of material properties on the crushing response has also involved. For the tensile test, it was concluded that the PLA/CF specimen offered the higher young modulus with 428.75 MPa than 360.76 MPa of PLA specimen. For the quasi-static compression test, the compressive modulus and strength of the single honeycomb sandwich panel showed 489.69 MPa and 18.32 MPa with boundary type 1, which provided the highest value compared to other two boundary condition types. Moreover, the square honeycomb sandwich panels with PLA/CF material and type 3 boundary condition offered the better crushing performance on energy absorption (EA) with 66.42 kJ and specific energy absorption (SEA) with 2282.47 kJ/kg. In addition, the crushing behaviour and failure mode were also involved and discussed in this study.

The effect of aluminum foams with different cell structure on the quasi-static compression behavior and energy absorption of aluminum tubular structures was investigated. For comparison, empty tubes and aluminum foams with different cell structure were also tested, respectively. The results indicated that the value of crushing peak load of aluminum foam-filled tubes increases from 57.88% (1.94mm cell size) to 89.33% (1.22mm cell size) respectively compared with 2.83mm cell size. Splitting deformation of foam filling was found to effect in increasing the extra contact between the foam filling and the tube during progressive crushing, which increases the lateral compressive forces on the tubes. The energy absorption of aluminum foams filled aluminum tubes was also improved significantly due to the change of cell structure.

Quasi Static Compression

Spent fuel transport cask is a significant carrier of spent fuel transport. The main function of impact limiters installed at both ends of the container is to absorb energy and limit overload to ensure the integrity of the structure. The quasi-static compression process of aluminum foam was simulated on the platform of ANSYS Workbench. Foam aluminum was prepared by melt foaming method and quasi static compression test was carried out. The experimental results show that the deformation process of aluminum foam is basically the same as that of experiment, and the aluminum foam has good compressive and energy absorption properties. The yield stress (σys) and plateau stress (σpl) of aluminum foam with density of 0.64 g/cm3 can reach 8.26 MPa and 11.11 MPa respectively, and the energy absorption capacity (WEA) and unit energy absorption capacity (WSEA) can reach 6.31 x 103KJ/m3 and 9.87 KJ/Kg respectively, and the difference between the foam with density of 0.61g/cm3 and its various properties is very small. It can be concluded that the aluminum foam in a certain density range has roughly the same performance, and it also reflected the stability of aluminum foam's performance. Additionally, aluminum foam is an isotropic material, which can overcome directional limitation when used as shock absorber filler material for spent fuel transport cask.
