Abstract
How large is the area of real contact when two solids are brought into contact? This fundamental question has interested scientists since the pioneering work of Hertz published 1882. The problem is of tremendous practical importance, since the area of real contact influence a large number of physical properties such as the contact resistivity, heat transfer, adhesion, friction and the wear between solids in stationary or sliding contact.
The focus of this thesis is the study the rough contact on micro scale between a rubber and steel surfaces. These surfaces are referred to a radial lip seal working on a rotational metal shaft. In this thesis this contact is studied using the Finite Element commercial software ABAQUS to study the elastic contact of reduced flat surface that represents the whole model of a radial lip seal in contact with a metal shaft. The other main goal of the thesis is to propose different methodologies to generate rough surfaces on a micro scale. These models for rough surfaces are generated using the SOLIDWORKS software. The simulation results are compared with the existing main theories that study this contact in order to achieve a better understanding of the micro scale surface contact mechanics.
