Abstract
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
