โœฆ Synopsis

Stiffened shells have been investigated for free vibration by using a stiffened shallow shell finite element. In the formulation the stiffener may take up any orientation within the shell element, and it need not necessarily be placed along the nodal line. A number of numerical examples of stiffened panels with various boundary conditions and five-bay skin-stringer structure, in addition to stiffened plates, have been presented. Results show good agreement with the available theoretical and/or experimental values.
