The present work is focussed on the free vibration analyses of singly curved sandwich beams using three-dimensional finite element method in ABAQUS software. Three different layers are considered for soft core and stiff face sheets in ABAQUS solid modelling to accurately represent the effects of transverse shear deformation of sandwich structure. To validate the model, obtained natural frequencies from present model are first compared with the results available in the literature for sandwich plates and are found to be in very good agreement. Several parametric studies are carried out to investigate the effect of aspect ratio, core to face thickness ratio and different layup of composite face on the free vibration of the curved sandwich beams with different boundary conditions. It is seen that the natural frequency decreases with the increase in aspect ratio, while, different orientations of composite face lamina have little impact on the same. Core to face thickness ratio and different boundary conditions affect the first few natural frequencies of the curved sandwich beams. Technique has been described for utilizing readily available commercial finite element software ABAQUS to enquire the vibrational characteristics of curved sandwich beam, one, which is less investigated till date but have structural importance.

Keywords: Free vibrations, curved beam, sandwich beams, finite element method, shear deformation.
