<p>PROBLEM TO BE SOLVED: To provide a defect detection method capable of detecting the internal defect of an inspection object whose inside has a complex shape such as a turbine wing and the inspection method of the turbine wing using the defect detection method.SOLUTION: A defect detection method includes: a load application process of repeatedly applying a load to the inspection site of an inspection object; and an inspection process of inspecting whether or not a crack based on the internal defect of the inspection object is exposed to the surface of the inspection object posterior to the load application process. It is desired that the stress analysis of the inspection site is performed, and test conditions and a test jig in the load application process are selected.</p> |
