The asymptotic analysis of free vibrations of a cylindrical shell joined with annular plates [PDF]

Известия Саратовского университета. Новая серия: Математика. Механика. Информатика
Low frequencies and vibration modes of a closed circular cylindrical shell joined with annular plates are obtained by means of asymptotic methods. Two types of vibrations, corresponding to narrow and wide plates, are analyzed. If the width of the ring is
