Development of empirical and damage predictive models, for protective structures, under extreme loading


School of Engineering

About the Project

Protective structures are the scarifying layers that can respond to severe loading, such as fire or explosion or missile impact or combination of such loads. The resulted dynamic deformation either in elastic or plastic region, is the scarifying mechanism by which , the main structure can be protected.

In this project , deformation modes of such protective structures under extreme loading will be investigated. Initially the Single Degree Of Freedom (SDOF) model will be revisited to include the accurate explosion overpressure pulses. Thereafter Multi Degree Of Freedom (MDOF) models and FEA , will be used to investigate on the corrections that is required in SDOF model. The project is aimed at developing empirical models for protective structures.

Upon acquiring the accurate models , substantial simulation with various design parameters will be carried out, from which deformation data can be collected. Considering dimensionless design parameters, as components of a feature vector, the optimization techniques similar to ones used in data since, would be implemented on the collected deformation data.

The outcome will be series of simple empirical formulas that can predict damage and deformation in protective structures. The applications of such empirical predictive models , can be very useful tool in designing blast resistant structures. Currently pressure impulse diagrams, are used to predict the damage and they are not conservative enough. This new model will be a promising alternative to the existing methods.

Candidates should have (or expect to achieve) the UK honours degree at 2.1 or above (or equivalent) in Mechanical, or Civil engineering.
An Engineering or Applied physics background that is related to structural dynamic is required. The applicant should have knowledge of modelling and simulation and fluency in one programming language like MATLAB, etc.
