説明
Fatigue crack tip opening stress σop and closing stress σct can be easily determined with the relationship between the following strain functions f, h and the cyclic stress σ, f=(εy-β)/(εx+α), h=εy+λεx, where εy and εx are the strains measured in the vicinity of the crack center (or the crack face), and α, β and λ are constants. With regard to small-size specimens having a center crack or notch, the accuracy of this measurement method is confirmed. If the constants α, β and λ are chosen to proper values, the crack tip opening stress σop and closing stress σot can be judged from the inflection points of the σ-h diagram and σ-f diagram. These stresses coincide with the opening stress σop and the closing stress σct determined by the unloading elastic compliance method.
