文摘

Analytical study of long elastic thin-walled rectangular hollow section struts. Nonlinear variational approach developed to model local-global mode interaction. Validation performed by nonlinear finite element model with excellent comparisons. Simplified expressions predicting secondary instabilities are developed.
