Research Studentship in Impact Engineering

Project: On the Response of Discontinuous Interfaces to Impact Loading

4-year DPhil studentship
Supervisor: Professor Daniel Eakins

This research project seeks to advance understanding of the behaviour of discontinuous interfaces when subjected to sudden, dynamic loading. This scenario can affect the safety and reliability of many high-performance engineering systems (i.e. engines, vehicle chassis, airframe), which contain a vast number of bolted/mechanically-affixed joints. The research project will provide the opportunity to develop a new experimental strategy, involving the mechanical design and commissioning of a bespoke impact testing platform, inspired by our existing suite of in-house gas guns. By using a combination of ultrafast diagnostics, which includes high-speed imaging, laser velocimetry, and X-ray imaging, details of the mechanics of complex interfaces during and after impact events will be used to provide validation of numerical modelling approaches. Typical phenomena of interest will include (but not be limited to) dynamic friction, surface finish, frictional heating, static, dynamic and modal response of bolted structures, and material/geometric non-linearity, etc. It is also expected that multi-scale effects and their importance in providing full structural understanding will need to be considered as part of this project. The ultimate destination for this work will be to inform the design of gas turbine engines for load cases such as Fan Blade Off where there is a multiplicity of bolted joints that affect directly the response of the structure and its ultimate integrity.

This project offers the opportunity to undertake fundamental research in the field of impact engineering, involving elements of materials science, mechanics, and ultrafast diagnostics.

Eligibility

This studentship is funded through the UK Engineering and Physical Sciences Research Council (EPSRC) Industrial CASE award and is open to Home students (full award – home fees plus stipend). Full details of the eligibility requirements can be found on the UK Research and Innovation website.

Award Value

Course fees are covered at the level set for Home students (c. £8290 p.a.). The stipend (tax-free maintenance grant) is c. £15285 p.a. for the first year, and at least this amount for three more years.
