✦ Synopsis

The natural frequencies and mode shapes of isotropic and linear elastic shallow hyperbolic paraboloidal shells of rhombic planform with free edges and corner point supports are calculated using a special finite element formulation. As a special case, the free vibrations of rhombic plates with corner point supports are examined. The effects of the skew angle and the curvature on the frequencies and mode shapes are investigated. The occurrence of curve veering phenomena is observed, and the relationship between these phenomena and the symmetry properties of the mode shapes is discussed.

An accurate method is presented for flexural vibrations of rhombic plates having all combinations of clamped and simply supported edge conditions. A specific feature here is that the analysis explicitly considers the bending stress singularities that occur in the two opposite, clamped-hinged and/or

A finite element analysis for the free vibration behaviour of point supported laminated composite cylindrical shells is presented. Eight-noded curved quadrilateral isoparametric elements are used. The formulation is based on the assumptions of the first order shear deformation theory for thin, shall

This paper is concerned with the free vibrations of circular cylindrical shells with rigid intermediate supports. The simplest form of thin shell theory according to Donnell and the reputed best first order approximation theory of Sanders are considered. An automated Rayleigh-Ritz method is adopted
