If a structure is subjected to a high - strain rate loading this effect should be considered in the material models that are used for numerical simulations. This article shows how t he strain - rate dependent material parameters can be determined by combining the experimental data with the numerical simulations. The presented methodology is based on an application of Taguchi arrays for finding the most adequate values for the strain - rat e dependent parameters. The presented methodology is applied on the practical case, for which the parameters of the Cowper - Symonds and Johnson - Cook material models are estimated"},{"@xml:lang":"sl","#text":"Za zmanjšanje stroškov raziskav in razvoja izdelkov (R&R), se v začetnih fazah razvojnega procesa uporabljajo kompleksna numerična vrednotenja in simulacije. Z njimi lahko napovemo, kako se bo izdelek obnašal v določenih obratovalnih pogojih. Za čim bolj točno napovedovanje obnašanja izdelka je potrebno izdelati 3D numerični model izdelka, poznati obratovalne pogoje in materialne lastnosti izdelka. Te lastnosti upoštevamo v konstitutivnih materialnih modelih, ki jih uporabljamo v numeričnih simulacijah. Zelo pogosto se v numeričnih simulacijah uporabljajo konstitutivni materialni modeli, pri katerih vrednosti njihovih parametrov ne moremo enostavno določiti. Zato je potrebno z izvajanjem eksperimenta in optimizacijskim postopkom poiskati ustrezne vrednosti parametrov konstitutivnih materialnih modelov. Optimalne vrednosti teh parametrov so tiste, pri katerih dobimo enak odziv izdelka kot v eksperimentu"}],"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-8KZTZFQK","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-8KZTZFQK"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-8KZTZFQK/85ba9a4e-d923-4a12-be2f-711d06b46574/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":"Univerza v Ljubljani, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-8KZTZFQK/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-8KZTZFQK"}}}}
