Buckling and vibration of laminated composite circular plate on Winkler-type foundation
B. Afsharmanesh, A. Ghaheri and F. Taheri-Behrooz

 
Abstract
    Buckling and vibration characteristics of circular laminated plates under in-plane edge loads and resting on Winkler-type foundation are solved by the Ritz method. Inclusive numerical data are presented for the first three eigen-frequencies as a function of in-plane load for different classical edge conditions. Moreover, the effects of fiber orientation on the natural frequencies and critical buckling loads of laminated angle-ply plates with stacking sequence of [(β / -β / β / -β)]s, are studied. Also, selected deformation mode shapes are illustrated. The correctness of results is established using finite element software as well as by comparison with the existing results in the literature.
