During the earlier examination of a similar model\u00a0\u2014 with equal coefficients of sliding and sticking\u00a0\u2014 only periodic steady-state solutions were found. In the present model, the two coefficients of friction are different. We show that this slight modification can lead to the occurrence of chaotic or transient chaotic behavior in certain parameter ranges, where the ratio of the sticking and sliding coefficients is quite large. Transient chaotic behavior is investigated in detail and finite time Lyapunov exponent is calculated. Moreover, a novel form of a sticking map is presented that enables the identification of nonsmooth bifurcations in the system.<\/jats:p>","DOI":"10.1142\/s0218127426300077","type":"journal-article","created":{"date-parts":[[2025,12,9]],"date-time":"2025-12-09T04:51:18Z","timestamp":1765255878000},"source":"Crossref","is-referenced-by-count":0,"title":["Nonsmooth Bifurcations and Chaotic Transients in a Simple Frictional Oscillator"],"prefix":"10.1142","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-4627-0205","authenticated-orcid":false,"given":"G\u00e1bor","family":"Licsk\u00f3","sequence":"first","affiliation":[{"name":"Engineering Calculations, Knorr-Bremse F\u00e9krendszerek Kft., 69 Major str., Budapest H-1119, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9559-761X","authenticated-orcid":false,"given":"G\u00e1bor","family":"Csern\u00e1k","sequence":"additional","affiliation":[{"name":"Department of Applied Mechanics, Faculty of Mechanical Engineering, Budapest University of Technology and Economics, M\u0171egyetem rkp. 3, Budapest H-1111, Hungary"},{"name":"HUN-REN\u2013BME Dynamics of Machines Research Group, Faculty of Mechanical Engineering, Budapest University of Technology and Economics, M\u0171egyetem rkp. 3, Budapest H-1111, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2025,12,9]]},"reference":[{"key":"S0218127426300077BIB001","doi-asserted-by":"publisher","DOI":"10.1007\/s11012-005-0409-x"},{"key":"S0218127426300077BIB002","doi-asserted-by":"publisher","DOI":"10.1016\/j.ymssp.2020.106734"},{"key":"S0218127426300077BIB003","doi-asserted-by":"publisher","DOI":"10.1063\/5.0138169"},{"key":"S0218127426300077BIB004","doi-asserted-by":"publisher","DOI":"10.1115\/99-GT-149"},{"key":"S0218127426300077BIB005","doi-asserted-by":"publisher","DOI":"10.1007\/s11012-021-01382-8"},{"key":"S0218127426300077BIB006","doi-asserted-by":"publisher","DOI":"10.1016\/j.jsv.2006.01.030"},{"key":"S0218127426300077BIB007","doi-asserted-by":"publisher","DOI":"10.1007\/s11071-006-9145-6"},{"key":"S0218127426300077BIB008","first-page":"107","volume":"53","author":"Den Hartog J.
