Abstract : The general objective of this research program is the development and application of new methods of analysis, numerical analysis, scientific computation and visualization techniques, within the context of specific nonlinear mechanics problems that model significant physical phenomena. In general mathematical terms the analysis and numerics can be classified as dealing with problems of continuation, bifurcation, and stability exchange as they arise in the variational principles of mechanics, and especially within the context of Hamiltonian systems. The fields of application all have these themes as common mathematical underpinnings, but the specific models are as diverse as describing gravity gradient effects on the attitude dynamics of large satellites, or the supercoiling and molecular dynamics of long chain macromolecules such as DNA. The guiding philosophy of the research is that substantial progress can be made by simultaneously considering context specific modelling issues along with the development of new and generally applicable analytical and numerical techniques. Within the project there is a particular emphasis on the exploitation of computation combined with interactive visualization to provide understanding of data, and to generate insight and conjectures that lead to analytical conclusions.
