Modal analysis of eccentric shells with fluid-filled annulus
Jhung MJ, Jeong KH, Hwang WG

 
Abstract
    Investigated in this study are the modal characteristics of the eccentric cylindrical shells with fluid-filled annulus. Theoretical method is developed to find the natural frequencies of the shell using the finite Fourier expansion, and their results are compared with those of finite element method to verify the validation of the method developed. The effect of eccentricity on the modal characteristics of the shells is investigated using a finite element modeling.
 
Key Words
