Abstract
Analysis of natural frequency and mode shape of a stiffened composite conoidal shell with cutout is done with the help of finite element method. Dynamic characteristics of stiffened composite conoidal shells with cutout are analysed for varying size of the cutouts and their positions with respect to the shell centre for different boundary conditions of cross-ply and angle-ply laminated composite conoids. The detailed effects of these parametric variations on the fundamental frequencies and mode shapes are considered. The results may be readily used by practising engineers for appropriate selection of stiffened composite conoids with the provision of cutouts either central or eccentric.
