This book focuses on the free vibrations of graphite-epoxy laminated composite stiffened shells
with cutout both in terms of the natural frequencies and mode shapes. The dynamic analysis of
shell structures which may have complex geometry and arbitrary loading and boundary conditions
is solved efficiently by the finite element method even including cutouts in shells. The
results may be readily used by practicing engineers dealing with stiffened composite shells
with cutouts. Several shell forms viz. cylindrical shell hypar shell conoidal shell
spherical shell saddle shell hyperbolic paraboloidal shell and elliptic paraboloidal shell
are considered in the book. The dynamic characteristics of stiffened composite shells with
cutout are described in terms of the natural frequency and mode shapes. The size of the cutouts
and their positions with respect to the shell centre are varied for different edge constraints
of cross-ply and angle-ply laminated composite shells. The effects of these parametric
variations on the fundamental frequencies and mode shapes are considered in detail. The
information regarding the behavior of stiffened shells with cutouts for a wide spectrum of
eccentricity and boundary conditions for cross ply and angle ply shells may be used as design
aids for structural engineers. The book is a significant contribution to the existing
literature from the point of view of both industrial importance and academic interest.
