Elastic buckling of radially loaded circular plates on nonaxisymmetric internal supports

This paper concerns the elastic buckling of radial, uniformly loaded, thin circular plates that are continuous over nonaxisymmetric internal line/ curved supports. The recently developed pb-2 Rayleigh-Ritz method [t] is used for the analysis. In the formulation, the entire circular plate is treated as a single continuum element, even when there are complicated internal curved supports. Because the pb-2 Ritz function is expressed as a product of two kinds of shape functions, one of which satisfies the plate. © 1993, Taylor & Francis Group, LLC. All rights reserved.
