우도구간(尤度區間)추정법에 의한 피로강도(疲勞强度)데이타 평가법에 관한 연구 = A Study on Evaluation Method of Fatigue Strength Data Using Likelihood Interval Estimation Method

다국어 초록 (Multilingual Abstract)

In estimating the fatigue data, only the uniform safety rate has been applied so far. However, since more reasonable design concepts such as machine structures or subsidiary materials will be required in the future, the importance of a statistical estimation method for fatigue data is being highlighted.
With such basic conception in mind, this study was aimed at critically discussing the interval estimation method which has been applied using the classical statistics thus far. It was conceived that this conventional method would result in the estimation of the unstable side from the viewpoint of the likelihood interval estimation method.
In this regard, this study aimed at estimating the fatigue strength through the likelihood interval estimation method comparing it with the eonventional interval estimation method would result in the estimation of the unstable side from the viewpoint of the likelihood interval estimation method.
One of the methods using the likelihood for estimation data is the Bayes method. Based on this theory, statistical estimations were positivly applied, and thereupon, the fatigue data were estimated.
