In this paper the flat rolling process is analyzed using the FEM and an analytical method in order to determine how the reduction, the velocity of the strip and the frictional coefficient affect the position of the neutral point. Both the analytical and FEM results are compared and we can say that analytical equations and the FEM modeling are in good agreement. The plane strain assumption is used in the FEM and in the analytical study, so, in order to study stress and strain, a two-dimensional mesh was considered for all the models. With such models, the deflection of the rolls for different strip thicknesses can be determined. The studied configuration is a four-high rolling system and the rolls and the strip are meshed in order to obtain theirstrain, stress, displacements and velocity fields</dc:description><dc:description xml:lang="sl">Raziskave na področju postopkov valjanja so izrednega pomena, kajti dejstvo je da je bilo veliko število izdelkov med postopkom izdelave vsaj enkrat udeleženo v postopku valjanja. V tem prispevku je analizirano ploskovno valjanje z uporabo analitičnih in metod MKE, z vidika določevanja vpliva zmanjšanja debeline in hitrosti valjanega tračnega jekla ter vpliva tornega količnika na lego nevtralne točke. Za primerjavo obeh rezultatov modeliranja (analitičnega in MKE) je moč skleniti, da so v dobri sodovisnosti. V obeh primerih modeliranja je predpostavljeno ravninsko napetostno polje. Na podlagi tega je bila za analizo napetostnega in deformacijskega polja ustvarjena 2-D mreža pri vseh obravnavanih modelih. S takimi modeli je moč določiti premike valjev za različne debeline valjanega tračnega jekla. Obravnavan proces je štirivaljno oporno valjanje, pri katerem so za analizo mreženi vsi deli z namenom modeliranja napetostnih in deformacijskih polj ter polj pomika in hitrosti</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-23CXGH10"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-23CXGH10" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-23CXGH10/a1c64b08-e1e2-4918-a748-4acfe71af00b/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Univerza v Ljubljani, Fakulteta za strojništvo</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-23CXGH10/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-23CXGH10" /></ore:Aggregation></rdf:RDF>
