The paper presents a new form of the stress criterion of multiaxial random fatigue. The criterion has been defined as a sum of normal and shear stresses with weight coefficients on the critical plane defined as the plane where the maximum covariance between shear and normal stresses occurs. Two forms of the criterion have been proposed.
