GBT-based structural analysis of elasticplastic thin-walled members
GBT formulation to perform first and second-order inelastic analyses of thin-walled members. Applicable to members exhibiting arbitrary local/distortional/global deformation patterns. Numerical results concerning five carbon/stainless steel members presented and discussed. Mechanical insight and numerical efficiency provided by the GBT modal nature illustrated. Accuracy of the GBT-based results assessed through comparisons with SFEA values.
