Abstract

A finite element is developed to analyse the vibration characteristics of initially stressed shells of revolution. The meridional, circumferential and normal displacements over the element are assumed to be cubic polynomials of the meridional co-ordinate. Numerical integration is used to generate the elastic stiffness, geometric stiffness and mass matrices. The element is used to analyse three typical problems pertaining to the vibrations of initially stressed thin shells of revolution.
