Interior residual stresses, which interact with the plane strain state, are more dangerous than residual stresses at the surface of the welded joint. If the surface of the welded joint is mechanically treated (e.g. shapering), then significant differences between the stress stated at the surface and within the volume occur. Hence, different non-destructive methods (e.g. gamma radiation, neutron diffraction) have been developed to determine strains caused by residual stresses in the volume of polycrystalline materials. However, the measurement of strains caused by residual stresses becomes difficult for large samples. In this paper the measurement procedure on a sample taken from the weld joint is presented and the effecet of residual stresses on fatigue crack propagation is assessed for low and high cycle loading fatigue"},{"@xml:lang":"sl","#text":"Porazdelitev in višina zaostalih napetosti lahko značilno vpliva na utrujenostno obnašanje zvarnih spojev in varjenje konstrukcije. Notranje zaostale napetosti so zaradi vzajemnega delovanja z ravninskim deformacijskim stanjem bolj nevarne od zaostalih napetosti na površini. V primeru če je površina zvarnega spoja mehansko obdelana (npr. brušena) se pojavijo izrazite razlike med zaostalimi napetostmi na površini in v notranjosti materiala. Zato so bile razvite različne neporušitvene metode (npr. gama sevanje, nevtronska difrakcija) s katerimi se določajo deformacije,ki so posledica zaostalih napetosti v polikristalnih materialih. Zaradi omejene penetracije nevtronov (do 20 mm) postaja meritev napetosti problematična pri večjih debelinah. V članku je predstavljen postopek meritve deformacij na iz zvarnega spoja izrezanih preizkušancih povzročenih z zaostalimi napetostmi in prikazan vpliv zaostalih napetosti na nizko in visokociklično utrujanje"}],"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-NI1K553G","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-NI1K553G"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-NI1K553G/dd0e2bfb-3d7a-42ee-a5a7-408f4ab1fbc8/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-NI1K553G/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-NI1K553G"}}}}
