Abstract

Cylindrical shell panels made of laminated composites with cutout are investigated for free vibration behaviour. Finite element model is used for studying the dynamic behaviour of stiffened shells using eight-noded curved quadratic isoparametric element for shell and a three-noded beam element for stiffener. Size of the cutouts and their positions with respect to the shell centre are varied for different laminations and edge constraints. The results presented in the form of figures and tables are analysed to suggest guidelines for selection of optimum size and position of the cutout with respect to shell centre considering different laminations and practical boundary conditions.
