In this respect, any full-scale industrial experiments appear non-acceptable. Cutting off the R&D costs and fast introducing of new technologies is possible when physical and numerical simulations are used. The computer simulation can be only correct when exact data of materials behaviour at processing conditions are known. To obtain the data, physical simulation is needed and it must be executed on multi-purpose thermal-mechanical testing devices accurately reproducing the real industrial processing conditions. For continuous casting or metal forming, individual phases of processes or multi-step operations must be followed, characterized by their time, temperature, and by applied forces, strains and strain rates. Actually the physical simulation, as compared with full-scale industrial testing, allows in a fraction of time for a fraction of cost an improvement of existing technology or development of a new one for modern materials and products. It can be used for solving production problems due to solidification phenomena or deformability limits, which result in hot cracking and rejection of the product. In this paper several examples of physically simulated procedures are given and their physical background discussed"},{"@xml:lang":"sl","#text":"Rast zahtev po boljših in bolj učinkovitih metalurških procesih stimulira po vsem svetu intenzivne raziskave, kako doseči te cilje, ker so za tak namen nesprejemljivi realni industrijski poizkusi. Zmanjšanje RR-stroškov in hitro uvedbo novih tehnologij dosežemo, če uporabimo fizikalno in numerično simulacijo procesov. Računalniška simulacija je natančna, če uporablja prave podatke o vedenju materiala v procesnih razmerah. Da bi te podatke pridobili, je potrebna fizikalna simulacija, ki se izvrši na večnamenski termomehanični preizkusni napravi, ki natančno reproducira pogoje realnega industrijskega procesiranja. Za neprekinjeno litje in oblikovanje kovin je treba upoštevati različne faze procesov, ki se odvijajo v več stopnjah, ki jih karakterizirajo čas, temperatura in uporabljene sile, deformacije in hitrosti deformacije. Fizikalna simulacija, če jo primerjamo z industrijskim preizkusom v polnem obsegu, omogoči, da se v delcu časa za del stroškov doseže izboljšanje sedanje tehnologije ali razvoj nove za moderne materiale in proizvode. Uporabljamo jo lahko za rešitev proizvodnih problemov povezanih s strjevalnimi pojavi ali z mejnimi deformacijami, ki povzročijo vročo pokljivostin izmeček proizvodov. V tem članku predstavljamo primere fizikalno simuliranih procedur in razpravljamo o njihovem fizikalnem ozadju"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-BDY7LE0O","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-BDY7LE0O"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-BDY7LE0O/d87c0ead-91d1-4011-838f-16bad9f19a09/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Inštitut za kovinske materiale in tehnologije"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-BDY7LE0O/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-BDY7LE0O"}}}}
