In this paper the low and high cycle fatigue behaviour of ten structural materials is analysed interms of strain-life, stress-life and cyclic stress-strain curves. Push-pull, strain-controlled fatigue tests areperformed and then the experimental data are processed according to the Standards in force as well as followinga recent procedure proposed by the authors which ensures the compatibility conditions are satisfied. As a result,a three dimensional representation of the experimental data in a stress-strain-life diagram can be drawn. Thestress-life, strain-life and cyclic stress-strain curves are the projection of a unique three-dimensional curve ontothe co-ordinate planes.
