PhD Scholarship in Ultrasonic Machining of Composites for Hybrid Joining

Loughborough University is offering a PhD position in electrical engineering. The duration of this scholarship is 3 years. All students regardless of citizenship are eligible to apply for this position. Applications are invited up to February 27, 2015.

Applications are invited for a PhD studentship funded by the Graduate School to start in October 2015. The project will be based in the School of Mechanical and Manufacturing Engineering, and the Department of Aeronautical and Automotive Engineering at Loughborough University.

Hybrid joining – a combination of bolting/riveting with adhesive joining – can provide significant benefits in aerospace, automotive and energy applications. The drilling of composite laminates to facilitate riveting and bolting leads to various damage modes in composites. Of these damage modes, delamination is the most dangerous since it can result in a significant reduction in stiffness and load-carrying capacity, and its propagation can lead to the catastrophic failure of the structure.

Ultrasonically-assisted drilling (UAD) is a recently-developed technique, in which high-frequency (20 kHz) vibration is superimposed onto the movement of a standard drill bit in the axial direction, providing advantages including reduced drilling forces (reduction often in excess of 80 %) and improved quality of drilled holes when compared to conventional drilling (CD). UAD also achieves a reduction in entry and exit delamination size, but not in the expected proportion considering the observed reduction of drilling forces. A different mechanical process to that in CD may be driving the delamination in UAD, for example dynamic or thermal effects in addition to thrust and torque loads.

Benefits
The studentship provides a tax-free stipend of £ 13,863 per annum for the duration of the studentship plus tuition fees at the UK/EU rate. International (non-EU) students may apply but will need to find the difference in fees between those for a 'UK/EU' and 'international' student themselves.

Duration
The studentship is for 3 years and is intended to start in October 2015.

Application Requirements
Students will normally need to hold, or expect to gain, at least a 2:1 degree (or equivalent) in engineering. A relevant Master’s degree and/or experience in one or more of the following will be an advantage: fiber-reinforced composite laminates, structural or materials testing, structural mechanics, finite element modelling.

How to apply?
