These data can be transformed when the conditions of material, strength, geometry, surface and surface layer and loading mode in the fatigue critical areas are taken into account for constant and variable amplitude loading. The procedure of data transferability is discussed for the example of a randomly loaded truck stub axle where the failure criterion is the first detectable crack, and the local equivalent stress/strain and the maximum stressed/strained material volume are considered. In addition, several problems associated with fatigue life assessment under variable amplitude loading are discussed.enAchseAnrißaxleBauteilBemessungBetriebslastensimulationconstant amplitude loadingcrackdamage accumulationdata basedata transferDatenbankDatenübertragungDehnungdesignEinstufenbeanspruchungFahrzeugbaufailure criterionfatigue life estimationforging partgekerbte ProbeLastLastfolgeLastkraftwagenLebensdauerabschätzungloadload sequencelocal stressMaschinenbaumaterial propertyMehrstufenbeanspruchungmetalMetallnotched specimenörtliche SpannungProbestabrandom loadingSchadensakkumulationSchmiedestückSpannungSpannungsanalyseSpannungsdehnungsverhaltenspecimenStahlsteelstrainstressstress analysisstress strain behaviorstructural componenttesttruckungekerbte Probeunnotched specimenvariable amplitude loadingvehicle constructionVersagenskriteriumVersuchWerkstoffeigenschaftzufallsartige Beanspruchung620report
