The break-up of glazing panels is a complex phenomenon for all bar the simplest quasi-static load cases. When subject to violent and transient blast forces, the fragmentation behaviour becomes substantially more difficult to mathematically model, quantify and predict. Solutions are highly dependent upon an intricate construct of non-linear material parameters, fracture mechanics, support conditions, harmonics and coupled load-response interaction. A window damage algorithm for blast effects has been tentatively proposed for a 50% probability of breakage based upon a prior series of experimental trials. In addition, statistical functions have been derived to describe the numerical spread of the breakage probability distribution. After scrutiny, it has been found that the breakage algorithm is only valid for a limited range of glazing configurations. There are additional issues pertaining to its empirical basis in the absence of any further theoretical development. The breakage hypothesis is further constrained by the reliance upon peak overpressure as the primary dependency and not total blast impulse.

This research project will build upon an on going advanced programme of experimentation and computational modelling to further understand the breakage variability of modern laminated glass assemblies due to high-power air blast. The research has the enthusiastic support of an internationally renowned science organisation and active research group, including special access to privileged test facilities. This doctoral project would suit a talented and motivated graduate in Civil & Structural Engineering, Mechanical Engineering, Applied Physics or Applied Mathematics. A passion to learn complex computational structural dynamics and computational fluid dynamics techniques to solve engineering problems is very important; combined with enthusiasm to conduct well thought out supporting experiments focused upon a clearly defined goal.
