SOME OBSERVATION ON FATIGUE PHENOMENA IN A LARGE PLATE SPECIMEN OF SPRING STEEL AFTER SHOT-PEENING TREATMENT

To obtain the fundamental data for the nondestructive finding of fatigue damage in vehicle parts, the fatigue due to pulsating repeated bending in a large plate of spring steel which had been shot-peened to increase its fatigue strength as a vehicle part, was investigated. It was clarified that there were two ways to find the fatigue damage: to observe the changing state of the surface residual stress and to detect the internal cracks non-destructively.
