Course detail

Interfacial Mechanics and Biotribology

FSI-ZIB-AAcad. year: 2014/2015

The overall aim of the course is to provide students with theoretical and applied knowledge of contact mechanics, gait analysis, lubrication mechanism, friction and wear mechanism that take place in natural and artificial load carrying joints, and play important role in designing and evaluating an artificial hip or knee implants, and their testing simulators. The course is focused on the following topics: gait analysis and contact mechanics of articular joints; tribology of natural diarthrodial joint; designing parameters of load carrying implants and testing simulators; experimental and computational procedures of biotribology; evaluation process of prosthesis performances of by means of friction wear and generated debris.

Aims

The course introduces the fundamental theories of biotribology and the scope of their applications in Mechano-biology. Interfacial mechanics and biotribology of major load carrying joints such as Knee, Hip are taught by classroom-based lectures, which will be accompanying by demonstration of experiment and computer simulation. Thus student will be able to analyse the design parameters of medical implants.

Specification of controlled education, way of implementation and compensation for absences

Attendance at lectures is recommended, but mandatory during scheduled quiz. The way of compensation for an absence is fully at the discretion of the teacher.
