Research Theme:  Structures & solid mechanics

Blast and its interaction with structures is a complex phenomenon even in the simplest quasi-static cases. This complexity is magnified when dealing with long duration blast loads and the added non-negligible ballistic parameters of dynamic pressure and the associated aerodynamic drag loads. Modelling the response of structures in such extreme environments is complex and a non-trivial process. After the breakage limit of a structure has been surpassed, the debris becomes entrained in a non-uniform flow field with varying drag coefficients. The particle size, number of fragments, orientation, distribution and ballistic properties of the debris require further important research; focused towards reliably quantifying current empirical predictions for long blast wavelengths. Existing hypotheses are additionally 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 debris distribution of complex masonry or segmental structures 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.
