The mathematical modelling of dry friction forces result in strong nonlinear equations of motion. The bifurcation behaviour of a deterministic system has been investigated by the bifurcation theory. The stability of stationary solutions has been analyzed by the eigenvalues of the Jacobian. Period doublings and Hopf-bifurcations as well as turning points could be determined with the program package BIFPACK. Phase plane plots of periodic and chaotic motions have been shown for a better understanding of the bifurcation diagrams. Both, unstable branches and stable coexisting solutions have been calculated. Several jumping effects, which are typical for nonlinear systems, have been found."}],"publication":"Bifurcation and Chaos: Analysis, Algorithms, Applications","doi":"10.1007/978-3-0348-7004-7_44","series_title":"International Series of Numerical Mathematics / Internationale Schriftenreihe zur Numerischen Mathematik / S{\\'e}rie Internationale d'Analyse Num{\\'e}rique","language":[{"iso":"eng"}],"date_updated":"2022-01-06T07:04:05Z","intvolume":"        97","title":"Bifurcations in Dynamic Systems with Dry Friction","year":"1991","publication_identifier":{"isbn":["978-3-0348-7006-1"]},"author":[{"full_name":"Stelter, Peter","last_name":"Stelter","first_name":"Peter"},{"full_name":"Sextro, Walter","first_name":"Walter","last_name":"Sextro","id":"21220"}],"citation":{"ieee":"P.
