Abstract:

Koiters well-known buckling analysis of cylindrical shells with periodic axisymmetric imperfections yields a solution which is valid for imperfection of different wavelengths and amplitudes. Numerical calculations were carried out to evaluate several of these cases. Of particular interest are imperfections of the wavelength which are larger than the one considered in Koiters original analysis. In such cases, the validity of the solution may be extended to imperfection amplitudes of a much larger order of magnitude hitherto considered. The numerical results are plotted and tabulated. A rederivation of Koiters analysis is added in an appendix together with a brief description of the computational method that was used. Author
