Modelling energy localisation and propagation in nonlinear lattices

The aim of this project is to investigate the frequencies and type of wave which permit the transfer of energy through a lattice.
In a nonlinear lattice, nodes are connected to nearest neighbouring nodes by force interactions which are nonlinear in local displacements. In addition, there may be internal degrees of freedom in which complicate the dynamics. Such systems can be modelled mathematically using large systems of coupled differential equations. Depending on the form of interaction and internal modes at lattice sites, energy can propagate through a structure, or be prevented from being transported, depending on the frequency of oscillations. The aim of this project is to use asymptotic analysis and numerical simulations to investigate these systems. The engineering applications of this work include the transport of energy from earthquakes across foundation piles which support buildings, as well as the propagation of such energy up a towerblock.
