Der Einfluss der Kerbgeometrie auf das Ermu Èdungsverhalten von Biegeproben aus der Aluminiumlegierung AA7075 wird im LCF-Bereich untersucht. Neben der kontinuierlichen Aufnahme der Kraft und der Durchbiegung als Zeitfunktionen wird das Risswachstum in den gekerbten Biegeproben mit dem Gleichstrom-Potentialsondenverfahren (PSV) erfasst. Zur Bestimmung der Spannungs-und Dehnungsverteilungen sowie der Dehnschwingbreite im Kerbgrund werden Finite-Elemente-Simulationen mittels des nicht-linearen isotrop-kinematischen Modells nach Chaboche und Lemaitre bestimmt. Anhand der FE-Rechnungen wird die Anrisslebensdauer nach der effektiven Dehnschwingbreitenhypothese ¹ASME Boiler and Pressure Vessel Codeª abgescha Ètzt und der plastischen Energiedissipationshypothese gegenu Èbergestellt.Schlagwort: gekerpte Biegeproben, Aluminium AA7075, Kurzzeitermu Èdung, Rissenstehung, Risswachstum, mehrachsige Ermu Èdung, Lebensdauervorhersage.Pulsating 3P-bending fatigue tests are conducted on edgenotched specimens of AA7075. Measurements of electrical potential drop across notches were used to determine the number of cycles up to crack initiation. Cyclic material data determined from strain±controlled constant amplitude loading are use in FE-analyses to the determination time functions of the local stresses and strains at the notch root using non-linear material model according to Chaboche and Lemaitre. Using these FE computations, the fatigue life is predicted by the equivalent strain approach of the ªASME Boiler and Pressure Vessel Codeº and compared with the results of the plastic strain energy approach. It is found that both approaches lead to relatively good predictions.

The paper introduces a valuable new description of fatigue strength in relation to material properties and thus a new perspective on the overall understanding of the fatigue process. Namely, a relation between the endurance limits and the accompanying values of the critical resolved shear stress (CRSS) for various metallic materials has been discovered by means of a multiscale approach for fatigue simulation. Based on the uniqueness of the relation, there is a strong indication that it is feasible to relate the endurance limit to the CRSS and not to the ultimate strength, as often done in the past.
