Due to their lightweight, porous and excellent energy absorption characteristics, foam honeycomb materials have been widely used for filling absorbing devices. For further improving the performance of novel tube proposed in our recent work, nonlinear dynamics software Abaqus was firstly establish verify simulation model aluminum-filled tube. Then, crashworthiness honeycomb-filled tubes, foam-fi...

Aluminum foam that is lightweight with high specific strength, energy absorption and other characteristics can be used in aerospace, transportation, machinery manufacturing fields. The PCM method usually to prepare closed-cell aluminum foams. microsized foams made by this process solve the non-uniform pore structures caused liquid drainage during foaming of large surface morphology internal str...

Studies of the crushing behavior of closed-cell, aluminum foam-filled aluminum and steel tubes have shown an interaction effect between tube wall and foam filler [1, 2, 3]. The crushing loads of foam-filled tubes are, therefore, found to be higher than the sum of the crushing loads of foam (alone) and tube (alone) mainly due to this effect. Santosa et al. [1], based on FEM results, proposed the...

The mining chute is an important equipment in the process of coal transportation and coal screening preparation. During the working process, the mining chute will generate a lot of vibration and noise because of constantly friction and impact of gangue and coal blocks. In order to reduce the vibration and noise during the operation of the chute, a new type of foam aluminum laminated structure i...

In the Lost Foam Casting process, melting point temperature of metal, as well as volume and rate of the foam degradation have significant effect on the mold filling pattern. Therefore, gas generation capacity and gas gap length are two important parameters for modeling of mold filling time of the lost foam casting processes. In this paper, the gas gap length at the liquidfoam interface for a lo...

Abstract Aluminum foam sandwich (AFS) is an innovative material combination for designing lighter products and has many advantages such as a high bending stiffness at low density good energy absorption properties. Although the ready series production, number of industrial applications because costs material, lack design knowledge missing reference applications. This paper focuses on aspect how ...

Potential applications of metal foams include light weight cores for sandwich panels, shells and tubes where the foam can increase the resistance to local buckling, increase the impact resistance, and improve the energy absorbing capacity of the structure [1,2]. This latter property offers potential uses in transportation applications where, for example, foam-filling of the hollow sections of a...

-Methods for producing metal foams are many, but obtaining repeatability in the properties is very difficult. The main challenge posed by the metal foam is that obtaining homogeneous porosity. Although lot of problems involved in the development of metal foams, research people are attracted to the metal foams because of its attractive properties like acoustic damping, bomb mitigation, light wei...
