The simulated results visualise dynamic evolution of equivalent stress, especially inside the work-piece. It is shown that the non-uniform distribution of equivalent stress on the longitudinal and transverse sections is a distinct characteristic of the processing tube tension-reducing, which can be used as basic data for improving tool and technics design, predicting and controlling the micro-structural evolution for manufacturing oil well tubes</dc:description><dc:description xml:lang="sl">Za simulacijo zmanjševanja napetosti cevi za naftne vrtine iz novega jekla 33Mn2V smo uporabili metodo končnih elementov. Simulirani rezultati predstavljajo dinamični razvoj primerjalne napetosti, še posebno znotraj obdelovanca. Razvidno je, da je spremenljiva porazdelitev primerjalne napetosti po vzdolžnem in prečnem prerezu izrazita značilka zmanjševanja napetosti naftnih cevi, kar lahko uporabimo kot osnovni parameter za izboljšanje orodja in tehnike, napovedovanje in regulacijo mikro-strukturnega razvoja za proizvodnjo cevi za vrtine</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-9H0FFXBT"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-9H0FFXBT" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-9H0FFXBT/ea9c07a1-0774-4504-a3a0-2a7d79989dff/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-9H0FFXBT/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-9H0FFXBT" /></ore:Aggregation></rdf:RDF>
