Therefore the influence of notch position and weld geometry on deformation initiation and further deformation is not sufficently well known. As a censequence, an enhanced defect assessment of welded components is not possible. Due to recent developments in field-measurement techniques, in computer technology and specific programs it is now possible to obtain detailed information about the quantitative deformation in base and weld metal in an effective and economic manner. In this contribution the analysis with laserspeckleinterferometry is described. Furthermore, computer-assisted laserspeckleinterferometry is applied to SENT specimens with different notch positions in the higher strength weld metal. With laserspeckleinterferometry the quantitative deformation performed in base and weld metal under the influence of the 45°-yielding starting from the crack tip, was measured. The possible evaluation for laserspeckleinterferomerty in terms of total deformation, partial deformation and deformation perfoprmed during single steps of the experiment are demonstrated. From the results the influence of notch position and weld geometry on the deformation behaviour could be evaluated. The consequences for the analytical determinataion of the yield load for welded joints, as input for defect assessment, are derived"},{"@xml:lang":"sl","#text":"S klasično tehniko preizkušanja, kot je merjenje povprečnega pomika z merilnikom ali pa kvantitativnim merjenjem pomika s pomočjo površinske metode na izbrani površini preizkušanca, se lahko pridobi samo omeje informacije o zvarjenem spoju. Zaradi tega je informacija o vplivu položaja zareze in geometrije zvara na iniciranje in nadaljnji potek deformacij nepopolna, kar onemogoča popolnejšo oceno napak zvarjenih spojev. Zahvaljujoč sodobnemu razvoju površinske tehnike merjenja, računalniški tehnologiji in programski opremi je sedaj možno na gospodaren in učinkovit način dobioti podrobne informacije o kvantitativni deformaciji v osnovnem materialu in zvarjenem spoju. V tem prispevku je opisana analiza z laserspeckleinterferometrijo. Na SENT preizkušanci z različimi položaji zarez v visokotrdnemu zvaru je uporabljena metoda računalniško podprte laserspeckleinterferometrije. S to tehniko je kvantitativno merjena deformacija v osnovnem materialu in zvaru pod vplivom 45° linije tečenja iz konice razpoke. Prikazano je vrednotenje z laserspeckleinterferometrijo v obliki skupne in delne deformaacije ter deformacij dobljenih v posamičnih korakih eksperimenta. Na osnovi rezultatov vpliva položaja zareze in geometrije zvara je možno oceniti deformacijske lastnosti. Zasledovane so posledice za analitično določanje sile tečenja za zvarjeni spoj kot vhodni podatek za ocenitev napak"}],"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-0Z18FY5Z","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-0Z18FY5Z"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-0Z18FY5Z/03141b1f-3844-4dc9-afda-100cad4a2e34/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-0Z18FY5Z/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-0Z18FY5Z"}}}}
