Abstract
The paper is devoted to the experimental assessment of the Refined Zigzag Theory (RZT) for the free-vibration analysis of sandwich beams. To investigate the model performance, the effect of the face-to-core stiffness and thickness ratios as well as beam slenderness are taken into consideration. For comparison purposes, the results obtained by using the Timoshenko’s beam model, adopting an adequate shear correction factor, are given. The RZT demonstrates its remarkable accuracy with respect to the Timoshenko’s beam theory even when the latter is used with the ad-hoc calculated shear correction factor.
