Abstract: | We present the results of a comparative study on the static deformation of a pallet, made from oil-palm fiberreinforced composite
material, using the phase-shift shadow moiré method and finite-element analysis (FEA). The pallet was designed and analyzed
using a commerical software package. The effect of various joint types on the deformation profile was studied to obtain a
simplified model to represent the actual design. A one-fifth scale model of the pallet was fabricated and the deformation
due to static loading was measured using the phase-shift shadow moiré method. The comparison between the measurement and FEA
results on the deformed profile showed a maximum difference of 13.7% at the center of the some of the deck boards, but a smaller
difference at other deck boards. The FEA results also produced a larger deformation gradient compared to the measurements. |
