Design and Fabrication of Rotationally Tristable Compliant Mechanisms
… is to develop the tools necessary to create tristable compliant mechanisms; the work presents the creation of models and concepts for design and a demonstration of the feasibility of the designs through the fabrication of tristable compliant mechanism prototypes on the macro scale. Prior …

Elementary morphing shells
… this behaviour is provided. In the lab, a novel tristable shell is constructed from a laminate and the use of specialized materials is scrutinised. In a subsequent project, a bistable spherical cap made from a customized material is actuated by a magnetic field—the ensuing snap-through event is …

From Pine Cones to Minimal Surfaces: The Geometry and Mechanics of Morphing Bilayers
… term with edge effects, we uncover a novel tristable structure and demonstrate how it can be straightforwardly fabricated in a table-top experiment. By use of soft elastomers, we investigate the one- and two-dimensional de-localisation of the boundary layer, noting a minimal surface for …

Travelling waves in Lotka-Volterra competition models
In this thesis, we study a class of multi-stable reaction-diffusion systems used to model competing species. Systems in this class possess uniform stable steady states representing semi-trivial solutions. We start by considering a bistable, interaction, where the interactions are of classic …
