Project Description:
Fretting wear is ubiquitous in virtually all rotating machinery and vibration-rich structures, for instance in gas turbines (incl jet engines). It is fundamentally different from sliding wear in that debris particles tend to remain inside the contact for much longer or permanently. There are no reliable predictive tools for fretting wear, meaning that friction joints tend to be conservatively designed and machines unnecessarily heavy. Few experiments have been done which explore this phenomena, yet data from these are required for any new modelling tools. Only recently has a new generation of experimental tests and new modelling approaches begun to tackle the fretting wear problem.


It is estimated that if the 100k+ contacting joints in a modern jet engine were to be redesigned using a robust fretting wear model the weight savings would be of very significant value.


Development of new modelling tools by Prof CW Smith, in conjunction with a world leading gas turbine manufacturer, have identified  a strong need for new experiments and new modelling tools to predict fretting wear. Prof CW Smith at Exeter has a unique bespoke fretting wear test facility and some excellent equipment for debris particles analysis. He is also developing new hybrid FE-DE methods aimed at tackling the particle and solid problems at the heart of fretting wear.
Fully funded PhD students are sought in the area of Discrete Element and Finite Element modelling, and fretting wear testing.
