- Abstract
This paper presents an experimental setup for the evaluation of the lateral deflection of a three-material composite beam subjected to a concentrated force. The three materials used in this setup are steel, aluminum and wood. In this experiment, two layer-bonding methods were considered: glued and bolted. In the glued configurations, the three stacked up layers were attached to each other using glue commercial along the beam length. For the bolted system, the layers were connected using four symmetrically-distributed bolts and nuts. The experimental results of the beam lateral deflections, for both bonding methods, were compared to theoretical computations. Comparison results showed that the glued system deflection data were in better agreement with theory. Also in this paper, the equivalent section method was implemented to solve for the composite beam bending stresses. Finally, the effect of the key geometric and material parameters of the composite beam on the beam bending stress is thoroughly investigated with the emphasis on the structural analysis of electronic assemblies subjected to mechanical bending loading.
