Generally characteristic of the machine of materials used for a structure, shape, use environment or use time are related to a machine and the destruction of the structure complicatedly and have it. I tend to be caused by metal fatigue to have by compression from load, pulling repeatedly then, and the early detection of the metal fatigue is important to prevent destruction. In addition, it is an important problem that a prediction senses the development of the crack of materials having the pettiness defect again because a microcrack occurs from the defect, and it progresses when there is a minute defect to the constitution member of the structure in the manufacturing process in fatigue destruction, and it tends to be it with a fatigue ruination. Therefore I perform a fatigue test with the minute defect materials that applied crack detection paint in this study and examine the microcrack detection precision that I used crack detection paint for from those results.
