20.500.12556/RUL-137286 Fatigue life prediction of butt weld joint with weld defects at multiple locations Napovedovanje časovne trdnosti sočelnih zvarov z napakami na več mestih A numerical model developed using finite element software is used to determine the fatigue life of an arc-welded butt joint with weld defects: lack of penetration, lack of fusion, and undercut, which occur predominantly in welded structures. High-strength, tempered, and quenched fine grain ASTM A517 grade F structural steel, widely used in welded structures, is selected as the base material. The finite element analysis approach adopted in the present work is validated using the experimental and analytical results by performing a benchmark study. The validated numerical approach is then used to generate datasets for developing an empirical model for predicting the fatigue life of a butt joint with defects, modelled as cracks at specific locations, subjected to bending and/or membrane stresses. An experimental investigation was undertaken to validate the empirical model. The influencing parameters are ranked based on their severity on the fatigue life of butt joint. butt joint weld defects fatigue loading fatigue life sočelni spoji napake v zvarih rast razpok utrujenostne obremenitve časovna trdnost true false true Angleški jezik Slovenski jezik Članek v reviji 2022-06-09 12:09:40 2022-06-09 12:09:42 2022-09-15 04:14:54 0000-00-00 00:00:00 2022 0 0 Str. 350-358 no. 5 Vol. 68 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2022-01-01 539.422.24 0039-2480 10.5545/sv-jme.2021.7536 111038211 Shaji_..._-_Fatigue_Life_Prediction_of_Butt_Weld_Joint_with_Weld_Defects_at_Multiple_Locations.pdf Shaji_..._-_Fatigue_Life_Prediction_of_Butt_Weld_Joint_with_Weld_Defects_at_Multiple_Locations.pdf 1 A8D124A755B1EE983703A010ACF64C32 0975b7bcc913b8221b536a0ca05e8b626007819f0b9e898cdca49e4b263adac2 51b81376-e7dc-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=157199 https://www.sv-jme.eu/sl/article/fatigue-life-prediction-of-butt-weld-joint-with-weld-defects-at-multiple-locations/ 1 1f9dd8a6-e7dc-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=157197 Fakulteta za strojništvo Strojniški vestnik 0 0 0
