On the other hand, the newly derived variable amplitude fatigue data will enable a reduction of wall thickness in future constructions, as the allowable fatigue strength values are significantly higher than in the case of constant amplitude loading.enApparatebauBeanspruchungconstant amplitude loadingDauerfestigkeitEinstufenbeanspruchungendurance limitequipment constructionFahrzeugbaufatigue lifefatigue strengthFertigunggekerbte Probelaser weldingLaserschweißenLebensdauerloadingmachine buildingmanufacturing processMaschinenbaumaterial characteristicsmaterial propertyMehrstufenbeanspruchungmetalnotched specimenPunktschweißenrostfreier StahlSchweißenSchweißverbindungSchwingfestigkeitSpannungspot weldingStahlstainless steelsteelstresstestvariable amplitude loadingvehicle constructionVersuchwelded jointweldingWerkstoffWerkstoffeigenschaftWerkstoffkennwert620conference paper
