| Summary: | Laminated sandwich structures exhibit high strength to weight and stiffness to weight ratios and therefore find wide application in aerospace applications where weight saving is a major consideration. Such composite laminates when integrated with piezoelectric layers form a smart structure and may be used for vibration and shape control applications. Since these applications often require the structures to be subjected to dynamic loadings, their vibration response analysis become an important design aspect. A detailed parametric study for the vibration analysis of laminated sandwich plates is presented in this work. The influence of aspect ratio, boundary conditions and thickness ratios on the free vibration response of the sandwich panel is studied. The plate is modelled using commercial FE package ANSYS. An eight-nodded shell-91 element is used to model the composite laminates, solid-5 element is used for modelling the piezoelectric layers and a solid-95 element is used to model the core. The efficiency and accuracy of the used elements is established by validation of the results with the published literature. All the results are presented with a converged mesh size. |
