The vibrational characteristics and mechanical properties of shell structures are discussed. The subjects presented are: (1) fundamental equations of thin shell theory, (2) characteristics of thin circular cylindrical shells, (3) complicating effects in circular cylindrical shells, (4) noncircular cylindrical shell properties, (5) characteristics of spherical shells, and (6) solution of three-dimensional equations of motion for cylinders.
A theoretical analysis is presented for treating the free vibrations of submerged, ring stiffened cylindrical shells with simply supported ends. The effects of the eccentric stiffeners are averaged over the thin-walled isotropic cylindrical shell. The energy method is utilized and the frequency equation is derived by Hamilton's Principle. All three degrees of freedom are considered. Numerical results are presented for frequencies for several cases of interest. (Author).
A method of analysis and a computer program were developed for determination of the frequencies and mode shapes of the free vibrations of stiffened cylindrical shells. The shells are stiffened by closely spaced stringers and rings, have different boundary conditions, and are subjected to either a static axial load or a hydrostatic pressure. The stiffeners are considered 'smeared' over the shell. The system of equations which was obtained is solved by a method known as the 'exact method'. The theoretical investigation includes a study of the variation in frequencies and mode shapes with increase in the static load until buckling. The results of the present analysis are compared to those of other methods which appear in the literature, and good agreement is obtained. (Author).
