The paper outlines developments to an exact strip postbuckling analysis, which improve the accuracy of mode shape, stress and strain calculations. Governing equations are derived and solved for general anisotropic plates with fixed, free and straight in-plane edge conditions. The improvements are validated by comparison with finite element results.
