Interrogation (probing) of Configuration Space in Buckled Structures

Abstract

This research proposal is focused on investigating the configuration space of post-buckled slender structural components. When subject to hostile operating environments, for example in a hypersonic flow regime, the surface skins of aircraft typically experience extreme axial loading conditions caused by thermal gradients and often precipitating buckling phenomena. It is crucial to understand the variety of possible shapes taken up by structural components under changing conditions, since the initial ‘natural’ shape taken up by the component is by no means unique. That is, there are typically a variety of co-existing shapes to which the component can be perturbed into, given appropriate disturbances. Interrogating, or probing, this highly nonlinear configuration space is the primary thrust of this research proposal.
