Abstract

The free vibration of curvilinearly stiffened cylindrical shells is studied by using the finite element method. The first order shear deformation theory (FSDT) is employed for both the shell and the Timoshenko beam modeling. The stiffener is assumed to be perpendicular to the shell. A local coordinate system consisting with the tangential, geodesic and normal directions is introduced to model the stiffener. Interpolation functions are used to build the displacement mapping between the stiffener and the shell nodes to allow the stiffener to be placed anywhere within the shell. Numerical examples shows that the present FE method can obtain precise enough results with a lesser number of elements as compared to the commercial software Nastran.
