Beschreibung

Initial situation:
Whenever two solid objects are in contact under certain load, deformation will occur. Since surfaces are not ideally smooth on the micro level, the actual contact will only occur on a certain number of asperities which will carry the load. What is the pressure at those asperities and can it cause elastic or plastic deformation are questions of interest in the field of Contact mechanics.

Content:
The aim of this study is detailed comparison of two existing numerical models for computing contact pressure between rough surfaces. The following should be answered:

  • What are the differences in results between the two models for different geometries and for a range of different operating conditions?
  • What are the advantages and disadvantages of each considered model?
  • Is extension of the considered models possible?
Voraussetzungen
