Reliabilityanalysis of structures based on fracture mechanics requires knowledge on statistical few experimental data have been reported on variability of m and C. In the present paper, axial fatigue tests were conducted on 30 specimens of 2024-T3 Al alloy under the same one condition. The values of m and C were determined for each specimen, and all the data were analysed statistically. The method for predicting the distribution of fatigue crack propagation life was also examined. The principal results are summarized as follows.(1) m follows a normal distribution approximately.(2) C follows a log-normal distribution approximately.(3) A strong linear correlation exists between the so-called pivot point (K0, C0) is considerably apart from the centroid of the data points, and therefore, it seems that the variation of m and C as well as their correlation do not arise from the intrinsic nature of the regression line.(5) Strictly speaking, C0 in the relation C=C0K0-m is not a fixed value but a random variable which is independent of m, and in the first approximation C0 follows a log-normal distribution.(6) The distribution of fatigue crack propagation life was calculaributed random variables. The calculated distribution was in good agreement with the experimental distribution.
The effects of the food intake pattern on the activity and fraction pattern of serum ƒÁ-glutamyl transpeptidase (ƒÁ-GTP) were examined in 257 healthy Japanese men.
