Abstract

This work aims to increase a slender structure's load-carrying capacity above its buckling point by introducing small imperfections, informed by post-buckling analysis of the unperturbed structure, known as 'modal nudging'. Specifically, we focus on structures with constrained geometry, such as wing panels, exemplified through a case study on Roorda frames.
