VIBRATIONS OF FREELY-SUPPORTED ORTHOTROPIC CYLINDRICAL SHELLS UNDER INTERNAL PRESSURE

Abstract

The influence of orthotropicity and internal pressure on the natural frequencies of a thin cylindrical shell whose ends are freely supported is found using the shell equations of Washizu. Other common shell theories are also presented. Calculations are performed for four constant thickness orthotropic cylinders, two stiffened cylinders, and a basic isotropic cylinder. For these calculations, only the special cases of axial and circumferential stiffening were considered.
