The elasto-plastic constitutive model at the macro-scale combines isotropic and kinematic hardening with continuum damage. This permits relatively precise modelling of the critical regions in the tooling systems over a large number of loading cycles. The macroscopic stress-strain fields are coupled with representative volume elements at the micro-level, where interactions between the primary carbides (M6C, MC, V8C7) and the martensitic matrix are evaluated. This provides a detailed insight into the stress-strain fields at the micro-level and reveals the damage mechanisms at the micro-scale. The performance of the model is demonstrated on an industrial example of a tool for the cold precision forming of metals</dc:description><dc:description xml:lang="sl">Predstavljen je numerični model za analizo cikličnih napetostno-deformacijskih odzivov in razvoja poškodb orodnih jekel na različnih dimenzijskih skalah po metodi končnih elementov. Makroskopski elasto-plastični konstitutivni model povezuje izotropno in kinematično utrjevanje s poškodbami kontinuuma. To omogoča razmeroma natančno modeliranje kritičnih območij v sistemu orodij za veliko število obremenitvenih ciklov. Makroskopska napetostno-deformacijska polja so povezana z reprezentativnimi volumenskimi elementi na mikroravni, kjer analiziramo medsebojne vplive med primarnimi karbidi (M6C, MC, V8C7) in martenzitno osnovo. S tem dobimo podroben vpogled v napetostno-deformacijska polja in poškodbene mehanizme na mikroravni. Uporabnost mikro-makromodela je prikazana na industrijskem primeru orodja za natančno preoblikovanje kovin v hladnem</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-TL770NBJ"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-TL770NBJ" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-TL770NBJ/be120b36-9016-4c6d-8337-6eb289be8ea0/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">Inštitut za kovinske materiale in tehnologije</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-TL770NBJ/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-TL770NBJ" /></ore:Aggregation></rdf:RDF>
