Image-Based Methods for the Dynamics of Ceramic Interfaces in Ballistic Armour Applications

The Ministry of Defence (MOD) Defence and Security PhD scheme has a current focus on ‘Novel Materials for Defence’. As part of this program, interfaces between armour ceramics and polymers/metals have been identified as key to improving the performance of ballistic armour for military personnel and vehicles. However, there is currently minimal understanding of the underlying physics of interfaces at impact loading rates due to a lack of experimental data.

The aim of this project is to develop new image-based methods for analysing the properties of ceramic interfaces under dynamic loading. This will be based on techniques developed by the PhotoDyn research team (http://photodyn.org/) using ultra-high speed imaging (> 1 Million fps). The project will include a significant experimental component using state-of-the-art imaging and impact facilities commissioned for the PhotoDyn research group. A combined approach of simulation and experiments will be used to adapt existing methods to the specific challenges associated with testing bi-material interfaces. During this project the candidate will receive extensive training in full-field displacement measurement techniques; high strain rate impact testing methods and ultra-high speed imaging.

The ideal candidate for this project will have a bachelor degree in mechanical, materials or civil engineering and have studied solid mechanics at undergraduate level. Prior experience with finite element simulations is desirable but not essential. Due to funding restrictions candidates must be UK/EU nationals.
