- GS15 Statistical Distribution and Estimation of Mechanical Properties of Austenitic Stainless Steels
抄録
To design structures, material strength properties are required, and these properties are dispersed. If this dispersion can be evaluated properly, the design margin can be set theoretically and at a reasonable cost In general, the minimum strength is specified when the steels are obtained. In the present report, strength data of austenitic steels are obtained, and the statistical distributions of the steels are considered using normal distribution and 3-parameter Weibull distribution. Also, strength at high temperature is considered. In the results, the distributions of 0.2 % proof strength of austenitic steels can be expressed as both normal distribution and 3-parameter Weibull distribution, and the shape parameter of the Weibull distribution is related to the cumulative distribution expressed by the normal distribution with location parameters expressed by the Weibull distribution, and the strength at high temperature is related to the chemical compositions. From the results, guidelines for assessing the probability of fracture of structures can be obtained.
