Experimental and Theoretical Deflections of Hybrid Composite Sandwich Panel under Four-point Bending Load
Abstract: This paper presents
a comparison of theoretical and experimental deflection of a hybrid sandwich
panel under four-point bending load. The paper initially presents few basic
equations developed under three-point load, followed by development of model
under four-point bending load and a comparative analysis between theoretical
and experimental results. It was found that the proposed model for predicting
the deflection of hybrid sandwich panels provided fair agreement with the
experimental values. Most of the sandwich panels showed theoretical deflection
values higher than the experimental values, which is desirable in the design.
It was also noticed that the introduction of intermediate layer does not
contribute much to reduce the deflection of sandwich panel as the main
contributor for the total deflection was the shear deformation of the core that
mostly determined by the geometric of the samples and the thickness of the
core.
