Free vibration frequencies of prismatic thin shells [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика
The paper examines the natural frequencies of prismatic thin shells, the cross-section of which is the regular polygon. Spectra of free vibration frequencies of such shells are analyzed as the number of cross-section sides increases, provided that the ...
