Abstract

Abstract

The double singularities induced by bifurcation point and boundary layer in nondimensionalized nonlinear boundary-layer Karman-Donnell equations for axiallycompressed stiffened cylindrical shells can be treated by Koiter-boundary layersingular perturbation method in this paper.Based on the analysis of AS-2 shell,it is demonstrated that the method hashigh computing efficiency and accuracy and some new conclusions can be directiy obtained from the perturbation formulas.
- singular perturbation theory,
- stiffened cylindrical shells,
- buckling and postbuckling
