Übertragbarkeit von Werkstoffkennwerten am Beispiel eines betriebsfestauszulegenden geschmiedeten Nutzfahrzeug-Achsenschenkels
Abstract
For the development of new components, design engineers today have access to a broad amount of fatigue data, which were obtained from unnotched and notched specimens. 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.
