“…In an early work at Opole University by the group of Ewald Macha, an equivalent uniaxial stress is determined from the general multiaxial stress state with irregular (possibly random) time courses by using classic static strength criteria, like that of the maximum principal stress (Galileo–Rankine), maximum shear stress (Tresca), deviatoric strain energy (Huber–Hencky–Mises), total strain energy (Beltrami). The main drawbacks in using these static criteria are highlighted in the paper of Macha and coworkers . In particular, it is shown that, in the presence of non‐proportional loading, these criteria do not account for rotating principal stress directions.…”

Nowadays, the estimation of fatigue life under multiaxial random loading is still an extremely complex task. In this paper, a comprehensive review of the multiaxial random fatigue criteria available in the literature is presented. Such a review is mainly devoted to stress‐based criteria for the evaluation of fatigue life in high‐cycle regime. Time and frequency domain approaches are examined. The focus of this paper is related to uniform stress/strain distribution, but also the effect of stress/strain gradient is tangentially addressed. More than 200 references are cited.

ABSTRACT. Professor E. Macha devoted his academic life to solving the problems connected with random multiaxial fatigue in components of machines and structures. In his studies he formulated stress, strain and energy criteria related to critical plane concept. He also proposed several methods to determine critical plane position. In particular, he formulated and verified weight functions applied in order to determine critical plane position. The variance method constituted another significant contribution to the development of methods for determining critical plane position. Apart from these criteria, Macha was exploring energy approach in fatigue of materials and the development of fatigue cracks. He has also observed that strain characteristics multiplied by stress amplitude determined at specimen half-life are applied to estimate fatigue life using energy criteria. However, for cyclically instable materials, stress amplitude value may differ a lot; therefore he proposed the method to determine energy fatigue characteristics directly from experimental research.

“…In [9] it has been shown that the criteria for variable amplitude loadings must be linear in order to avoid an unfavorable wide frequency band and the mean value occurrence. In [19] Macha formulated the generalized fatigue criterion in stress approach.…”

In this paper generalized criteria of multiaxial random fatigue based on stress, strain and strain energy density parameters in the critical plane have been discussed. The proposed criteria reduce multiaxial state of stress to the equivalent uniaxial tension-compression or alternating bending. Relations between the coefficients occurring in the considered criteria have been derived. Thus, it is possible to take into account fatigue properties of materials under simple loading states during determination of the multiaxial fatigue life. Presented models have successfully correlated fatigue lives of cast iron GGG40 and steel 18G2A specimens under constant amplitude in-phase and out-of-phase loadings including different frequencies.
