000016024 520__ $$2eng$$aTo obtain tribological parameters like Archard's wear depth parameter kd usually requires some severe effort in performing and analyzing complex tribological experiments. The paper features an approach where such parameters are extracted from effective interaction potentials [1], which themselves are built up and fed from more physical-oriented measurements like Nanoindentation and PHYSICAL scratch. By using such effective material potentials one can derive critical loading situations leading to failure (decomposition strength) for any contact situation. A subsequent connection of these decomposition or failure states with the corresponding stress or strain distributions allows the development of rather comprehensive tribological parameter models applicable in wear and fatigue simulations as demonstrated in this work. From this a new sophisticated wear model has been developed on the basis of the effective indenter concept [1, 2] by using the extended Hertzian approach [3, 4]. The models do not only allow to analyze certain tribological experiments like the well known pin-on disk test or the more recently developed nano-fretting tests, but also to forward simulate such tests and even give hints for better component life-time predictions. The work will show how the procedure in principle is to be applied and a few examples will be presented in the corresponding talk.
