Course detail
Advanced Tribology
FSI-9EHD Acad. year: 2022/2023 Both semester
The subject provides theoretical and practical knowledge regarding processes of friction, lubrication and wear which take place in machines with essential importance in its research, development and production. Attention is paid on student’s understanding of basic and advanced principles and its application to research and development of tribological systems. The subject follows up and complements content of subjects in the Master’s study in the fields of tribology, mechanics, mechanical engineering and material sciences.

Prerequisites
General courses on mechanics, machine design, material sciences and hydromechanics.
Planned learning activities and teaching methods
Lectures, discussions and self-study.
Assesment methods and criteria linked to learning outcomes
Conditions for gaining the exam:
- submission and defense of individual work on selected theme related to the field of contact problems, lubrication, friction or wear. The work includes theoretical description, calculations and analysis of own or published experimental results.
Aims
Absolvents are able to analyse and solve advance problems of friction, lubrication and wear of contacts in machines. Focus is payed on improvement of abilities to understand, describe and interpret own observations of tribology experiments and simulations.
Specification of controlled education, way of implementation and compensation for absences
