|(In Japanese)発明の名称||CRACK PROGRESS INHIBITING METHOD|
PROBLEM TO BE SOLVED: To propose a new method for further effectively inhibiting a progress of cracks from a stopping hole by applying a compression stress to a tip of the stopping hole processed at a tip of a crack.
SOLUTION: In this crack progress inhibiting method, a stopping hole 2 is provided at an end of a slit so as to inhibit propagation of fatigue cracks. A hole 3 is provided around the stopping hole 2, and an inner pressure is loaded to the hole 3, so as to generate a compression stress to a crack generating portion 2B of the stopping hole 2.
