Abstract

Ovaj rad obrađuje teorijske metode koje daju rešenje za nelinearne probleme kontakta sa trenjem, a koja proizilaze iz fenomena prianjanja - klizanja. Cilj istraživanja jeste predviđanje napona i deformacija na kontaktnoj površini, kao i unutar komponenti koje dolaze u kontakt, pošto se površina kontakta menja progresivno usled uvođenja spoljnjeg opterećenja. U radu se polazi od pretpostavke da su materijali linearno elastični dok su pomeranja i deformacije male, a površina kontakta kontinualna i ravna. Pretpostavlja se, takođe, da ne dolazi do međusobnog probijanja površina tela u kontaktu. Rad se zasniva na metodi konačnih elemenata prilagođenoj problemima kontakta, na inkrementalno-iterativnoj metodi i na savremenim matematičkim teorijskim postavkama za rešavanje ovog problema. / This paper elaborates theoretic methods which give solutions for nonlinear problems of contact with friction that arise from stick-slip phenomenon. The aim of the study is anticipation of tension and deformations on the contact surface as well as inside of components that come in contact, because contact surface is changing progressively owing to outer load induction. In this paper it is presumed that materials are linearly elastic, while motions and deformations are minor, and contact surface is continuous and plane. It is also presumed that it does not come to mutual perforation of the objects surfaces in contact. The paper is based on finite elements method, modified for contact problems, on iterative-incremental method and with contemporary mathematical theoretical assumption for contact problem solving.
