PROBLEM TO BE SOLVED: To provide an instrument life evaluation technology capable of performing a highly accurate evaluation of the structural damage of an instrument due to creep fatigue damage, and thereby capable of highly accurate instrument life evaluation.;SOLUTION: In the instrument life evaluation system 10, the instrument life evaluation method for evaluating the instrument life due to the structural damage of the instrument based on creep or fatigue considers the structural damage of the instrument based on creep or fatigue as the development of fine cracks and lets a computer process the evaluation of the instrument life by predicting the development of these fine cracks.;COPYRIGHT: (C)2010,JPO&INPIT
