Abstract (en)
Thesis presents a study of the fatigue life of welded steel tubes made of API J55 steel, using the parameters of the fracture mechanics obtained on the basis of experimental research. At the same time, analyses the integrity using a FAD diagram and estimates the remaining life of welded tubes made of API J55 steel, based on experimental data, using the extended finite element method (XFEM) as one of the new calculation techniques integrated into the Abaqus software package. For simple geometries analytical methods are developed and applied.
Abstract (sr)
Teza predstavalja studiju procene zamornog veka zavarenih cevi napravljenih od API J55 čelika, koristeći parametre i svojstva mehanike loma, određenih eksperimentalno. Integritet cevi je određen primenom FAD dijagrama, na osnovu koga je procenjen i rizik od loma, koristeći originalnu metodu preko matrice rizika. Preostali vek je određen takođe na osnovu eksperimentalnih podataka o koeficijnetima Parisov zakona za čelik API J55, primenom relativno nove numeričke metode, tzv. proširene Metode Konalnih Elemenata (pMKE), ugrađene u ABAQUS softver. Za slučaj jednostavne geometrije razrađena je i primenjena analitička metoda.

“Data exchange” service offers individual users metadata transfer in several different formats. Citation formats are offered for transfers in texts as for the transfer into internet pages. Citation formats include permanent links that guarantee access to cited sources. For use are commonly structured metadata schemes : Dublin Core xml and ETUB-MS xml, local adaptation of international ETD-MS scheme intended for use in academic documents.
