10 Credits AUTUMN

Aims/Description: The course begins by describing geometric (roughness) and material characteristics of surfaces. When two surfaces are pressed together under a load, contact is made at isolated spots. Analysis techniques to estimate contact areas, contact stresses and the resulting material behaviour are also taught. Lubrication (both fluid and solid) and bearing selection are also covered. These concepts are integrated by industrial lectures by using various case studies. 

Staff Contact: Dr Julia Carrell
Teaching Methods: Lectures, Tutorials, Laboratory work, Independent Study
Assessment: Formal Exam, Wear Assessment (20%)
