The cyclic properties of structural materials may be identified by means of mini specimens only. The method is limited by specimen geometry and test conditions. The mini specimens are characterised by low rigidity with a tendency to buckling. Within the range of stresses used, the tests may be based on a onesided cycle only, which eliminates compressive stress. It requires determination of symmetric stress cycles (R = -1) characteristics. An experimental σa-N curve for cycle with stress ratio R = 0.1 was determined based on mini specimen testing. The curve was further used to determine a curve for symmetric stress cycles R = -1 using selected mean stress models.
