Development of a Finite Element Model for the Class V Flextensional Underwater Transducer Shell.
Abstract
A Finite Element Model is developed for the Class 5 Flextensional Underwater Transducer Shell for various end boundary conditions. A doubly curved axisymmetric spherical shell element is utilized in order to predict the dynamic response of spherical shells. Novozhilov's 'Thin Shell Theory' is applied and the element stiffness and mass matrices are derived. The spherical shell is represented as a finite number of spherical frustra, joined at nodal circles. The equation of motion is wirtten for the free vibration problem. (Author)
