Multiaxial fatigue analysis is categorized into five viewpoints, . empirical formulas and modifications
of the Coffin-Manson equation, application of stress or strain invariants, use of the space averages of
stress or strain, critical plane approaches, and use of energy which has accumulated on the materials.
Garud ~ (J. Test. Evaluations 1981, 9, 165) reviewed the results of multiaxial fatigue researches proposed
up to 1980 in chronological order and evaluated them. In this paper multiaxial fatigue researches which
have been suggested after 1980 were classified into the five viewpoints and some problems which
existed in those studies were examined. During these periods major progresses in multiaxial fatigue
analysis are the consideration of anisotropy of materials and the suggestion of the energy method using
Mohr's circles. Additionally, existing equations or pa
