Design and implementation of a self-sealing specimen chamber to allow shock loading of hazardous materials

Overview

High velocity impacts on targets can generate shock waves which travel through the target material. The response of the material to such extreme impacts is of interest to many areas of engineering, in particular the defence sector. Gas guns are used to enable fine control over the shock loading of targets to study the material response. The goal of the research project is to enable the study of materials which cannot be currently studied in the UK.

Focus/Aim

The purpose of the project is to design and prove a self-sealing containment vessel that can be attached to the muzzle of a gas gun. This would enable the study of materials which would constitute a hazardous contamination risk if undertaken in an open laboratory. The containment vessel must be attachable to the gas gun in a manner that prevents damage to the gas gun, or the containment vessel, upon firing at velocities up to 1km/s.

Why Cranfield University?

The research will be undertaken at the Cranfield University’s Shrivenham campus (School of Defence and Security), on the site of the Defence Academy of the UK. CDS has decades of experience of gas gun experiments, including recovery systems which enable controlled shock experiments. 

Unique Selling Points

Whilst working closely with AWE colleagues, publication of results in open-source journals and travel to UK and overseas conferences will be encouraged.

What will you Learn?

As a PhD student, you will have the opportunity to develop strong independent thinking and research skills, focusing on qualitative research methodologies and ontology development. During your studies, you will also gain valuable experience in presenting the outputs of your scientific research at events and conferences. To support you in achieving a high standard in writing and presenting technical reports, scientific papers, and your thesis, the University offers a number of courses. These transferable skills will contribute to your academic development as well as enhance your employability prospects.

Expected Impact and Results

The resultant containment system will enable the safe exploration of the shock response of hazardous materials. This will be a unique UK capability. This will contribute knowledge to both the defence sector and in improvement of safety

What will you gain from the Experience?

The project will incorporate challenging aspects of mechanical design and material behaviour in extreme conditions. It also gives the opportunity to work with colleagues in AWE for those interested in employment within the MOD / defence industries.
