All fatigue tests were carried out at the Technical University of Ostrava mainly under block loading in order to determine the effect of stress amplitude and mean stress on the strain response of the material. Experimental results show that the critical value of the axial deformation is close to the ductility of the material investigated. The aim of this paper also is to draw important conclusions in terms of ratcheting modelling for the material investigated. Translation abstractde Der vorliegende Beitrag zeigt neueste Forschungsergebnisse im Bereich des Ratcheting-Verhaltens der Aluminiumlegierung 2124-T851 während uniaxialer Belastung. Alle Ermüdungsversuche wurden an der Technischen Universität Ostrava, vorwiegend unter Blockbelastung, durchgeführt, um den Einfluss der Spannungsamplitude und Mittelspannung auf die Dehnungsantwort des Werkstoffs zu untersuchen. Experimentelle Ergebnisse zeigen, dass der kritische Wert der Axialverformung sehr nahe an der Duktilität des untersuchten Materials liegt. Das Ziel der Arbeit ist auch wichtige Schlussfolgerungen im Sinne der Ratcheting-Modellierung des untersuchten Materials zu betonen.
