Analysis of natural vibration of truncated conical shells partially filled with fluid

International Journal of Mechanical System Dynamics, Volume 4, Issue 2, Page 142-152, June 2024.
The variation of natural frequencies of truncated straight and inverted circular conical shells partially or completely filled with an ideal compressible fluid was investigated based on the results of a numerical simulation. The solution of the boundary value problem was found by applying Godunov's orthogonal sweep method and integrating the coupled ...
