The Effect of Curvature on Transient Analysis of Laminated Composite Cylindrical Shells on Elastic Foundation

This study presents the effect of curvature ratio on transient vibration analysis of simply supported antisymmetric thick cross-ply laminated composite shells (LCS) on elastic foundation. In the analysis, the foundation is modeled with two parameters. These models are Pasternak and Winkler models. The equation of motion for laminated rectangular shells resting on elastic foundation is obtained through Hamilton’s principle. The analysis is achieved in Laplace domain. By using modified Durbin’s algorithm, calculations are transformed from Laplace domain to the time domain. The numerical results are presented in the form of graphics.
