Two geometries of specimens with different values of constraint were analyzed. Theexperimentally obtained results were compared with numerical data. The presented result makes it possible to relate experimentally measured data obtained from specimens with different geometries, and thus contributes to more reliable estimates of the residual fatigue life of a structureDvoparametrska vpetostna metoda je uporabljena pri problemu širjenja utrujenostne razpoke blizu praga propagacije. Analizirani sta dve geometriji preizkušanca z različno vpetostjo. Eksperimentalni podatki so primerjani z numeričnimi. Rezultati omogočajo, da se poveča eksperimentalne izsledke s preizkušancev z različno geometrijo in omogočajo bolj zanesljivo oceno preostale trajnostne dobe neke struktureTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
