This paper deals with fatigue assessment of metal beams under complex loading. Combined axial, bending and torsion loads are taken into account under assumption thet the material complies with the Kelvin-Voigt's model and has a fatigue limit, and the stress components are stationary stochastic processes whih are stationary correlated and differentiable in the mean-square sense. By taking the power spectral densities of the stress components for known the criterion of infinite fatigue life of beams is formuleted in the frequency domain. For this purpose the distortion-energy strength hipothesis and the theory of energy transformation systems are used.
