Abstract:

Analysis of 3D Sandwich Composite Panels (3DSCP) subjected to flexure is carried out using Finite Element Analysis (FEA). Analysis Model parts, input data and results are described. For the sake of model’s validation, Results of the analysis model is compared to published experimental test results. Effect of shear connectors on behavior of 3DSCP is studied. The analysis program consists of two series of 3DSCP samples with different aspect ratios. Volumetric ratio of shear connectors is increased by two ways. In first series, shear connectors’ diameter is increased. While in second series, spacing among shear connectors is reduced. Improvement in 3DSCP composite action is analyzed via strain distribution across the panel’s thickness. Other enhancements in 3DSCP behavior like load bearing capacity and deflection are investigated. Recommendation regarding effective method to increase 3DSCP load capacity is proposed.
