Opis:: The paper presents the comparison of experimental and calculated fatigue lives for EN AW-6082 T6 aluminium alloy. Hour-glass shaped specimens have been subjected to constant and variable amplitude uniaxial and multiaxial loadings, i.e. plane bending, torsion and their proportional combinations with zero mean values. Three multiaxial fatigue criteria based on the critical plane approach have been verified being the linear combination of shear and normal stresses on the critical plane. For the variable-amplitude loading, the rainflow cycle counting method and Palmgren-Miner hypothesis have been applied. The best fatigue criteria are pointed in the final conclusions.

Opis:: The paper presents comparison of three methods of fatigue life assessment related to aluminium alloys. One of these methods is a new way of statistical interpretation of the fatigue test results by means of the root of the mean-square value of the error expressing a half of scatter of the calculated fatigue life. The results of fatigue tests of specimens, and different geometries of welded joints made of aluminium alloys were considered. The calculated fatigue lives were obtained with use of critical plane orientations determined according to the variance of normal and shear stresses, and the covariance of normal and shear stresses.
