The paper presents the comparison of the results of experimental fatigue tests for the 6082-T6 and 2017-T4 aluminium alloys. Tests performed under two types of load conditions. That is tensilecompressive and oscillatory bending. The results are obtained by applying the Basquin's stress-life equation and strain-life equations: Kandil’s equation, Langer’s equation and the authors’ own equation. On the basis of own experimental studies and the relevant physical relations, the stress and strain amplitudes occurring in bent rods under smooth specimens, were calculated according to the elastoplastic model. The results were then used to compare both types of loads with different types of control.
