Research Fellow in Modelling of Wire-based Additive Manufacture

Cranfield University - School of Aerospace, Transport Systems and Manufacturing - Manufacturing/Welding and Laser Processing Centre

Fixed Term Contract for 3 Years
£32,656 to £36,399 per annum
Location: Cranfield, Bedfordshire

Cranfield University is an exclusively postgraduate institution and a global leader for education and transformational research in technology and management. It is one of the top five research-intensive universities in the UK and has an unrivalled reputation for transforming cutting edge technology, management and science into practical, life-enhancing solutions. In the last UK Research Excellence Framework (REF) over 80% of the research carried out by Cranfield University was assessed to be either world or internationally leading, indicating the quality and impact of the work carried out at Cranfield University.

Within the Manufacturing Theme, the Welding Engineering and Laser Processing Centre (WELPC) has been at the forefront of welding and Wire + Arc Additive Manufacture (WAAM) for over fifty years pioneering new techniques and material applications. We have a large research activity (≈£1.2 million per annum) which is funded from both government and industrial sources.  Cranfield University is currently a world leader in WAAM having pioneered new methods and techniques to successfully build large scale parts up to 6 m long. 

As a consequence of this successful research activity we have recently been awarded a large £5.7m project funded by EPSRC entitled New Wire Additive Manufacture (NEWAM).  This project will be conducted in collaboration with the University of Manchester (materials), University of Strathclyde (NDT) and Coventry University (structural integrity).  The project’s vision is to transform metal additive manufacture, by pioneering new high build rate wire-based processes to produce net-shape large-scale engineering structures.  To date, most of our deposition is done with arc based processes such as plasma welding.  To achieve the required step-change improvement in deposition rate and fidelity it will be necessary to develop hybrid arc-laser deposition methods with multiple arc and laser sources.  To facilitate development of these new processes, it is essential that the centre has an underpinning modelling activity to provide the intellectual basis for future process developments.  In particular it will be necessary to:

  • Understand and predict thermal interactions between multiple energy sources in the wire-based additive manufacture process
  • Develop fluid flow models for the evolution of deposit bead geometries with different energy profiles
  • Predict distortion and residual stress to allow optimisation of deposition strategies and facilitate new tooling designs.

The aim of this role is to extend our existing capabilities in these areas. You will be expected to carry out high quality research which will result in the production of high quality papers.  Good interpersonal skills will be necessary to liaise with work colleagues and academic partners involved in the NEWAM project. The research will include model development and investigation, and some experimental validation (although this will primarily be conducted by colleagues).  Assisting in the supervision of research and MSc students, and production of research proposals will also form part of the role.

You will need to have a PhD (or close to completion) in physics, materials science or mechanical engineering, ideally involving numerical modelling of manufacturing processes with fluid flow and/or finite element models. In addition, knowledge of laser processing, arc welding, metallurgy are desirable. You should have a demonstrable track record of high quality research or technology development. Experience of working with industry would also be beneficial.  The position will also require project management and supervising of research students (MSc) and technicians and the development of research proposals.

At Cranfield we value Diversity and Inclusion, and aim to create and maintain a culture in which everyone can work and study together harmoniously with dignity and respect and realise their full potential.
