Numerical analysis of aluminum foam sandwich subjected to compression loading
Demand using aluminum foam sandwich in
various application of industry keep increasing. Hence, the
reliable numerical models are still required and need to be
enhanced by observing the mechanical behavior of the sandwich
structure. Numerical analysis of aluminum foam sandwich that
subjected to compression loading had been analyzed using LSDYNA software. Three different thickness of aluminum foam
(3.2mm, 5.6mm, 6.35mm) and three different thickness of
aluminum sheet (0.4mm, 0.6mm, 0.8mm) had been selected to
investigate their pattern of force-displacement curves and energy
absorbed. The numerical results have been validated by
experimental results for comparison. The findings show that
simulation results exhibit good agreement with the experimental
results in terms of their trend in force-displacement curves and
deformation behavior of the sandwich structures. The increment
in peak force and energy absorbed affected by increasing the
thickness of foam and aluminum sheet
Flexural behavior of open-cell aluminum foam sandwich under three-point bending
Aluminum foam sandwich (AFS) panels are one of
an advanced material that has various advantages such as
lightweight, excellent stiffness to weight ratio and high-energy
absorption. Due to their advantages, many researchersโ shows an
interest in aluminum foam material for expanding the use of
foam structure. However, there is still a gap need to be filling in
order to develop reliable data on mechanical behavior of AFS
with different parameters and analysis method approach. There
are two types of aluminum foam that is open-cell and closed-cell
foam. Few researchers were focusing on open-cell aluminum
foam. Moreover, open-cell metal foam had some advantages
compared to closed-cell due to the cost and weight matters. Thus,
this research is focusing on aluminum foam sandwich using
open-cell aluminum foam core with grade 6101 attached to
aluminum sheets skin tested under three point bending. The
effect Skin to core ratio investigated on AFS specimens analyzed
by constructing load-displacement curves and observing the
failure modes of AFS. Design of experiment of three levels skin
sheet thickness (0.2mm, 0.4mm, and 0.6mm) and two levels core
thickness (3.2mm and 6.35mm). a full factorial of six runs were
performed with three time repetition. The results show that when
skin to core ratio increase, force that AFS panels can withstand
also increase with increasing core thickness
Experimental Study of Stress-Strain Behaviour of Open-Cell Aluminium Foam Sandwich Panel for Automotive Structural Part
Because of high stiffness and strength to weight ratio, aluminium foam sandwich (AFS) has huge advantage in automotive industries in order to reduce the vehicleโs weight which consequently will reduce the fuel consumption. While reducing the weight, AFS must also maintain high strength and durability compared to other competitive materials used which perform same functionalities. AFS had been proved its suitability for industrial application by previous researchers such as in aerospace, automotive and architecture. However, there is still a gap need to be filled in order to expand the use of the AFS in another application. In this paper, the tensile strength of AFS panel made of from aluminium skin sheets and open-cell aluminium foam core with various thickness is investigated. Design of experiment was developed according to JUMP (JMP) statistical software and experimental work was done using universal testing machine. The stress-strain behavior was analysed. The result shows that the effect of skin to core ratio is significant on the stress-strain behavior

In this paper, the tensile strength of AFS panel made of from aluminium skin sheets and open-cell aluminium foam core with various thicknesses is investigated. To achieve the objectives of the research, experimental work has been conducted. Full factorial of two independent factors: core thickness with two levels and skin thickness with three levels. JMP software (version 11) has been used to analyse the data. Experimental work was done using universal testing machine. The stress-strain behaviour was analysed. The result shows that the effect of skin to core ratio is significant on the stress-strain behaviour
