Abstract

Investigating the principle to select element size of structural wet surface in the FE-BE algorithm has a great significance.The structural bending wavelength of the main vibration mode of a finite length ring stiffened cylinder was computed with the wave number spectrum method to provide some principle for selection of element size of a structural wet surface.Numerical computation showed the effectiveness of the principle.

Key words
