Within the framework of the project, the relationship between frictional damping and mechanical damage (wear or fatigue) under fretting conditions is to be investigated systematically (numerically and experimentally). For example, is it possible to construct a tribological system that has a very high dissipation of mechanical energy and thus damping and yet is only slightly damaged? Possible (and relatively easy to implement in practice) approaches include optimizing the contact geometry or the type of loading.

The results of the project will be relevant to increase the lifetime of technical or biotechnological systems and thus save resources and effort for their reproduction.
