Besides the limitations which are the result of the IR camera itself and the thermal properties of the material detected, IR thermography produces acceptable results when combined with an appropriate numerical method. A numerical simulation of heat transport makes possible a separate analysis of the relevant parameters that characterize heat dissipation in the material, like the intensity and duration of the heat stimulation, the properties of the material and the starting conditions, as well as the time distribution of certain parameters. The comparison of a numerical simulation and thermographicmeasurements presented in 5 shows a very good agreement of the results. The importance of determining the moment when the contrast reaches its maximum can be clearly seen from the numerical analysis. The analysis alsoshows that a relative material loss and the diameter of the defect can be estimated with the best accuracy at the moment when the current contrast reaches its maximum"},{"@xml:lang":"sl","#text":"Uporaba infrardeče (IR) termografije kot neškodljiva preizkusna metoda za odkrivanje napak pod površino ter tudi za določevanje jakosti korozije veliko obeta. Razen omejitev, ki so posledica IR kamere same in toplotnih lastnosti preizkušanega materiala, nam da IR termografija v povezavi z ustrezno numerično metodo sprejemljive rezultate. Numerično simuliranje prenosa toplote nam omogoči ločeno analizo primernih parametrov, ki določijo razširjanje toplote v materialu, kot so: jakost in trajanje toplotnega vzbujanja, lastnosti materiala in začetni pogoji, prav tako pa tudi časovno porazdelitev nekaterih parametrov. Primerjava numerične simulacije in termografskih meritev, opisanih v 5, je dala zelo dobro ujemanje rezultatov.Iz numerične analize je jasno razvidna pomembnost določitve trenutka, ko kontrast doseze svojo največjo vrednost. Analiza nam prav tako pokaže, da lahko relativno izgubo materiala in premer napake določimo z največjo točnostjo v trenutku, ko kontrast doseže svojo največjo vrednost"}],"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-U2POR0LI","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-U2POR0LI"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-U2POR0LI/35dc638a-24d0-467b-8f9d-acb9554fdd14/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-U2POR0LI/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-U2POR0LI"}}}}
