Fatigue lifetime assessment of notched components under multiaxial variable loading based on a short crack growth concept.
Konferenzveröffentlichung, Bibliographie
Kurzbeschreibung (Abstract)
A short crack model originally proposed for multiaxial constant amplitude loading is extended and applied to cases of multiaxial variable amplitude loading. Load sequence influences that play an important role under variable amplitude loading are implemented based on some algorithms originally only proposed for uniaxial loading. Estimated Fatigue lives of unnotched tubular specimen and notched shaft under different in- and out-of-phase multiaxial constant and variable amplitude load histories are compared to experimental results. The comparison yields satisfying estimation accuracy for the presented short crack approach. Even the critical planes, planes of maximum crack growth or minimum crack growth life, respectively, are estimated with good agreement to experimental observations
