Abstract

The paper presents recent developments in exact strip postbuckling analysis for anisotropic plates with combined in-plane loading and various in-plane edge conditions. The analysis improves the accuracy of the postbuckling mode and the consequent prediction of stresses and strains in the postbuckling range. Plates are divided into longitudinal strips, for which the governing equilibrium equations are derived and solved analytically. Implementation of the improved analysis into the exact strip software VICONOPT enables accurate stress distributions to be found for each stage of the postbuckling analysis. Numerical results are presented and compared with previous results from VICONOPT and finite element analysis for validation.
