Hysteresis loops of austenitic steel cycled in symmetric and asymmetric strain- and stress controlled loading are analyzed to evaluate the contribution of effective stress and probability distribution of internal critical stresses. The austenitic-ferritic duplex steel is cycled with various positive mean stresses and cyclic stress-strain response, cyclic creep rates, resulting dislocation structures and fatigue life are evaluated. The effect of the mean stress on cyclic plasticity and fatigue life is discussed.
