Accuracy of the Buckling Predictions of Anisotropic Plates
The aim of this work is to explore the potential of two hierarchic sets, one polynomial and the other trigonometric, in the construction of versatile Ritz bases to accurately solve the linear buckling of anisotropic Kirchhoff plates. Focus is placed on reporting the basis ability to surmount numerical degrading effects associated with anisotropy. Several examples are presented to illustrate the merits and demerits of each set in terms of accuracy and rate of convergence, mainly by comparing their results with those obtained from traditional Ritz bases and finite-element models.
