概要
Thermal fatigue failure and vibration fatigue failure occur frequently in spite of well known. Because they are complicated multi-physics phenomena. Furthermore, there are many influence factors in both of loadings and strength. For design, conservative evaluation methods were applied to both loadings and strength. However, best estimation with uncertainty evaluation are suitable for trouble shootings and risk analyses. To satisfy above requirements, authors propose a total evaluation of loadings and strength for fatigue damage prediction, where realistic analysis models are utilized for best estimation and partial safety factors are applied to engineering uncertainty evaluation.
