20.500.12556/RUL-107393 Influence of geometry and safety factor on fatigue damage predictions of a cantilever beam The influence of two parameters on fatigue damage predictions of a variably loaded cantilever beam has been examined. The first parameter is the geometry of the cantilever beam and the weld connecting it to a rear panel. Variables of the geometry examined here include the cantilever length, the weld width on the critical cross-section and the angle of the critical cross-section. The second parameter is the safety factor, as set out by the Eurocode 3 standard. An analytical approach has been used to calculate the stresses at the critical cross-section and standard rainflow counting has been used for the extraction of the load cycles from the load history. The results here suggest that a change in the width and angle of the critical cross-section has a non-linear impact on the fatigue damage. The results also show that the angle of the critical cross-section has the biggest influence on the fatigue damage and can cause the weld to withstand fatigue better. The second parameter, the safety factor, is shown to have a significant effect on the fatigue damage calculation, whereby a slight increase in the endurance safety factor can cause the calculated fatigue damage to increase considerably. fatigue damage welded joint rainflow cantilever beam fatigue poškodbe utrujanje zvari konzole števne metode true false true Angleški jezik Slovenski jezik Članek v reviji 2019-04-10 13:14:42 2019-04-10 13:14:44 2022-08-19 03:49:18 0000-00-00 00:00:00 2019 0 0 Str. 33-41 no. 1 Vol. 70 Apr. 2019 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2021-04-05 539.43:620.178.3(045) 1225-4568 10.12989/sem.2019.70.1.033 16558875 15455749 RAZ_Pecnik_Matija_i2019.pdf RAZ_Pecnik_Matija_i2019.pdf 1 F999C736E6A41CEAF9736E1C258EB82D 3df08e0316371ec5762f96b42ba92c3576a272507a66fdaf25d6b3c9268b0d86 6c114475-a1b6-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=118208 http://www.techno-press.org/download.php?journal=sem&volume=70&num=1&ordernum=3 Dostop do polnega članka z geslom 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=118207 Fakulteta za strojništvo 0 0 0
