Abstract
The natural frequencies of cylindrically curved panels are available in closed form for only two boundary condition sets. Blevins demonstrated how Sewall’s shallow shell formation can be reformulated in a relatively simple form to allow direct calculation of the natural frequencies and mode shapes of cylindrical panels with a wide range of boundary conditions. This paper presents a free vibration analytical - numeric, through the finite element method, via ANSYS software, comparative study of a cylindrical panel with straight sides clamped and three boundary conditions of curved sides: clamped, simply supported without axial constraint and free.
