“…They used a nine-nodded isoparametric finite element for bending and free vibration of sandwich plates. On the other hand, a new three-dimensional (3D) layerwise finite element model with 240 DOFs has been developed by Nabarrete et al (2003) for dynamic analyses of sandwich plates with laminated face sheets. They used the FSDT for the face sheets, whereas for the core a cubic and quadratic function for the in-plane and transverse, displacements, was adopted.…”

“…A sample of selected papers published in recent years is given in the list of references, which review the state of the art and provide numerous cross-references on the subject, see Birman (2002), Sisemore and Darvennes (2002), Sokolinsky et al (2002), Choi (2003), Nabarrete et al (2003), Bozhevolnaya and Sun (2004), Kapuria et al (2004), Meyer-Piening (2004), Plagianakos and Saravanos (2004), Ruzzene (2004), Sokolinsky et al (2004), Ganesan and Pradeep (2005), Hao and Rao (2005), Numayr and Qablan (2005), Yang and Qiao (2005) and . One of the main reasons for conducting research in this area is due to the fact that sandwich constructions offer designers a number of advantages of which, perhaps the most important one is the high strength to weight ratio.…”

In this paper, an accurate dynamic stiffness model for a three-layered sandwich beam of unequal thicknesses is developed and subsequently used to investigate its free vibration characteristics. Each layer of the beam is idealised by the Timoshenko beam theory and the combined system is reduced to a tenth-order system using symbolic computation. An exact dynamic stiffness matrix is then developed by relating amplitudes of harmonically varying loads to those of the responses. The resulting dynamic stiffness matrix is used with particular reference to the Wittrick-Williams algorithm to carry out the free vibration analysis of a few illustrative examples. The accuracy of the theory is confirmed both by published literature and by experiment. The paper closes with some concluding remarks.

“…The dynamic behaviour of sandwich beams is well researched and the literature is around for nearly half a century (Birman, 2002;Sisemore et al, 2002;Sokolinsky et al, 2002;Choi, 2003;Nabarrete et al, 2003;Bozhevolnaya et al, 2004;Kapuria et al, 2004;Meyer-Piening, 2004;Plagianakos et al, 2004;Ruzzene, 2004;Sokolinsky et al, 2004;Ganesan et al, 2005;Hao et al, 2005;Numayr et al, 2005;. One of the most prominent properties investigated by number of researchers is the vibration analysis.…”

The dynamic analysis of jute-epoxy sandwiches with fly ash reinforced functionally gradient (FG) flexible, compliant rubber core is presented. FG samples are prepared using conventional casting technique. Presence of gradation is quantified by weight method. An attempt is made to study the influence of fly ash weight fraction, jute orientation and core to total thickness (C/H) of sandwich on damping ratio (DR) and natural frequency (NF). The design of experiments based upon L9 (3 3) orthogonal arrays by Taguchi is used. Analysis of variance (ANOVA) and S/N (signal to noise) ratios analysis is performed on measured data to investigate the influence of material and geometrical parameters on dynamic response. An optimal parameter combination is determined which leads to higher DR and NF. A correlation derived from the results of Taguchi experimental design is proposed as a predictive equation for estimation of these properties of sandwiches. These correlations are obtained by multiple regressions. It is demonstrated that the predicted results obtained using these equations are consistent with experimental observations.
