Optimum forming pressure for achieving uniform thickness in a complex three-stage radius dome profile has been established. Variations in thickness profile are observed experimentally and in FEM analysis in three different die entry regions. The thickness profile has also been predicted as a function of the friction coefficient and die entry radius. The changes in pole thickness, relative height and relative radius of the profile along with the thinning factor are discussed</dc:description><dc:description xml:lang="sl">Superplastično preoblikovanje je pomembna tehnologija, primerna za izdelavo delov kompleksnih oblik v eni sami preoblikovalni operaciji in z možnimi aplikacijami v avtomobilski industriji, v letalski in vesoljski industriji, ali pri izdelavi lopatic vetrnih in vodnih turbin. Pri takšnih aplikacijah je dobrodošlo vse obstoječe znanje in informacije o večstopenjskih (tristopenjskih) operacijah superplastičnega preoblikovanja. Ključno vlogo pri procesu superplastičnega preoblikovanja imajo dejavniki, kot so enakomerna porazdelitev debeline, preprečevanje čezmernega tanjšanja in večdimenzijske komponente brez gub. Enakomerna porazdelitev debeline večdimenzijskega profila je npr. nujna za določanje tlaka pri postopku pihanja</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-L90476P3"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-L90476P3" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-L90476P3/bbc0a808-c7b2-4d1f-a99f-22ca9a0c0c93/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-L90476P3/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-L90476P3" /></ore:Aggregation></rdf:RDF>
