摘要：

The paper presents application of the covariance extremum between normal end shear stresses for determination of the critical plane. The fatigue stresses criterion was formulated as a linear combination of normal and shear stresses on the defined critical plane. The weight coefficients occurring in this criterion were determined from fatigue tests in the layer of pure bending and pure torsion. The proposed model was verified while fatigue tests under cyclic proportional and non-proportional bending with torsion specimens made of aluminium alloy PA6-T4 were tested).
