“…They concluded that the natural frequencies of the laminated composite sandwich beam were increased with increasing the core thickness, shear modulus and with decreasing the density. Arvin and Sadighi [7] performed a numerical investigation on free and forced vibration of composite sandwich beam and they focussed the comparative analysis between free and forced vibration. Also they developed the governing equation of motion by accomplishing the higher order theory and by assuming independent transverse displacement on each layer.…”

In this paper, the vibration analysis of uniform laminated composite sandwich beam with a viscoelastic core was studied. The governing equation of motion of the laminated composite sandwich beam has been derived based on higher order shear deformation theory (HSDT) in finite element model (FEM IntroductionNowadays the demand for the sandwich structure is getting increased because of its high stiffness to the low weight ratio. It is also paved the attention of the researchers and scientist towards the sandwich structures. A Sandwich structure finds its place in wide range of applications because of its high stiffness and flexural rigidity especially in marine, aerospace and astronautics. Ibrahim Ozkol and AytacArikoglu [1] were made an investigation on vibration analysis of the uniform laminated composite sandwich beams with viscoelastic core using differential transform method. The governing equation of motion of sandwich beamwas formulated by Hamilton's principle and it was solved by differential transform method (DTM), Eigen value analysis method was used to generate and evaluate frequencies. Banerjee et al. [3] investigated the vibration characteristics of the viscoelastic material based asymmetric sandwich beam by using the dynamic stiffness model which was developed from the Timoshenko beam theory. Manoharan et al. [4] presented the finite element formulation of the magnetorheological (MR) fluid based sandwich beam. The governing equation of motion sandwich beam was formulated using finite element method. In this study it was concluded that the natural frequencies increased by increasing the intensity of the magnetic field irrespective to the boundary conditions. Allahverdizadeh et al. [5] was studied the dynamic behaviour of adaptive sandwich beams, where the middle layer as electro-rheological fluid (ERF) and constraining layers were fabricated by functionally graded materials (FGM). This study shows that the resonant frequencies and the amplitude of peak values have been decreased by increasing the thickness FGM at constant electric filed. From the results it was indicated that at a definite applied electric field, the Clamped-Clamped beam showed the higher resonant frequencies and the cantilever beam showed the least value among all end conditions. Xu and Qiu [6] studied the free vibration analysis and optimization method of composite lattice truss core sandwich beams. The partial differential governing equation of motion was developed by adopting the Hamilton principle which was based on Thimosenko and bernoullis beam theory and then the natural frequencies of the

“…Actually, the free dynamics behaviour of two-layer beams has been largely studied in the literature [12][13][14][15][16][17][18][19][20], where numerical [21,22], analytical/theoretical [8,23] as well as experimental [8,11,24,25] studies can be found. Also some specific issues have been investigated, such as, the effect of interface damage [8,26,27], the viscoelastic behaviour of the core [28][29][30], the effect of the temperature [31,32], the lateraltorsional vibration coupling [33], curved beams [34], and boundary conditions effects [35].…”
