Sonsino, C.M.C.M.Sonsino2022-03-092022-03-091997https://publica.fraunhofer.de/handle/publica/328263The development of fatigue loaded PM parts requires knowledge of material related design data such as S-N curves, influence of loading mode, notches, and mean stress sensitivity on one hand, and on the other hand knowledge of the service loading and the local stresses resulting in the most critical areas of the part. Comparison between the local and the allowable stresses shows whether the design can be implemented or further optimisation is necessary. The fatigue design procedure and its experimental verification is demonstrated by two case studies.enBauteilBemessungbendingBiegungDauerfestigkeitdesignendurance limitFahrzeugbaufatigue strengthfatigue strength testLastloadlocal stressmaterial propertymaterial selectionörtliche Spannungpowder metallurgyPulvermetallurgiesafetySchwingfestigkeitSchwingfestigkeitsversuchSicherheitSpannungsanalyseSpannungsverteilungspecimenstress analysisstress distributionstructural componentvehicle constructionWerkstoffauswahlWerkstoffeigenschaftWoehler curveWöhlerlinie620conference paper
