‘Development of Novel Low Energy Laser Shock Peening’

Faculty of Engineering, Environment & Computing

Prof M Fitzpatrick , Dr P Shukla , Dr D Tanoko Ardi Monday, May 10, 2021 Funded PhD Project (Students Worldwide)

About the Project

Coventry University and the Agency for Science, Technology and Research in Singapore (A*STAR) are inviting applications from suitably qualified UK/EU/international graduates for one fully-funded PhD studentship for the project ‘Development of Novel Low Energy Laser Shock Peening’. By engaging in research in the United Kingdom and Singapore, the programme offers researchers the opportunity to access to the state-of-the-art research facilities and advance their knowledge and expertise in the fields of materials and manufacturing engineering, whilst developing their intercultural skills and making international networks and collaborations.

 The Research Project

Useful life of metal components operating under dynamic stresses and severe environment conditions can be enhanced by peening the surface. Laser shock peening (LSP) is a surface enhancement method with a unique capability of generating deep compressive stressed layer (1 mm approx.) at low cold work resulting in excellent resistance to fatigue damage. The application of this process is largely limited to aero-engine and nuclear applications due to its high cost. Currently, LSP utilizes a high energy (~1-10 J) nanosecond pulsed laser with low frequency (~5-10 Hz). The aim of the proposed programme is to address the high cost associated with the use of high energy laser system in the current LSP by developing a novel low energy laser peening process (~100 mJ). With the recent development of fibre lasers operating in low energy regime, the laser systems have reduced requirement of the auxiliaries (optics system and cooling system) and compact size. This project will investigate the use of such fibre laser for peening applications in other industry sectors apart from aerospace and nuclear, with the effect almost comparable to that of current LSP.


The successful candidate will undertake research activities such as:

- Develop appropriate laser peening conditions by altering laser parameters, implementing new methods to increase plasma induced shock wave pressure, configuring the most appropriate beam spot shape and size and identifying the optimum viscosity of confinement medium.

- Demonstrate use of low energy LSP for new applications such as MEMS, thin sheets and microwelds.

- Measure and analyse surface characteristics, integrity, residual stress of peened components and compare it with that of conventional high energy LSP.

- Work with industry in applying the findings and developing the system for real application.


How will the joint programme work?

The successful candidate will enrol at Coventry University, UK as their home institution and will spend up to 2 years at the A*STAR Advanced Remanufacturing and Technology Centre (ARTC).


A typical 4-year pattern of attendance is shown below, although the actual plan of study and timings at each location will be developed in the light of the details of the proposed research project as defined in the early stages of the project, and with the mutual agreement of the supervision team.
