conference contribution
posted on 2011-08-04, 10:46 authored by Patrick Fenner, Andrew WatsonAndrew WatsonThe theoretical buckling performance of thin walled panels under compression can be
predicted using classical plate theory (CPT) and using tools such as the VICONOPT, which
uses the finite strip method, and Abaqus, a finite element modelling program (FEM).
VICONOPT is much more computationally efficient than FEM, and is able to optimise panel
design for buckling and pseudo-postbuckling performance. This work forms part of a larger
project to use VICONOPT to optimise panel designs that are allowed to buckle in a stable
manner below the maximum allowed loading. Because VICONOPT can only make a first
approximation of postbuckling performance, a method is required to validate the
optimisation results against a more accurate method.
