✦ Synopsis

This paper presents a method for the dynamic and static analysis of thin, elastic, anisotropic and non-uniform open cylindrical shells. The open shells are assumed to be freely simply supported along their curved edges and to have arbitrary straight-edge boundary conditions. The method is a hybrid of finite element method and classical shell theories. The shell is subdivided into cylindrical panel segment finite elements, the displacement functions are derived from Sanders' equation for thin cylindrical shells. Expressions for the mass and stiffness are determined by precise analytical integration.

The free vibration of open and closed cylindrical shells are studied by this method as well as anisotropic shells and shells having circumferentially varying thicknesses. The results obtained reveal that the frequencies calculated by this method are in good agreement with those obtained by others.
