Tribology and Contact Mechanics Group
Tribology is the study of surfaces and their interactions. These interactions include motion, contact, adhesion, indentation, friction, lubrication, fatigue and wear. This study is vitally important for a lot of different materials and their uses in a range of machinery and devices, at a range of scales. For example, the Group has specialised interest in larger scale contacts that occur in rolling element bearing and between the teeth of power transmission gears, as well as the tribology of nano devices.
The major research aim of the Group is to improve understanding of the gear distress phenomena of micropitting, scuffing and wear. Also, at the nano scale, research into the problems of contact and adhesion is being aided by pre-fractal representations of surface geometry.
Research projects are organised into the following three areas:
- Experimental studies of elastohydrodynamic lubrication (EHL) failure mechanisms, surface roughness and coatings, led by Prof R. Snidle
- Studies based on numerical analyses of fundamental and applied tribological problems, led by Prof H. P. Evans
- Fundamental contact mechanics of micro and nano scale tribological contacts, led by Prof F. M. Borodich.
