Abstract:
Residual stress distribution produced by shot peening was decreased in early time under fatigue test of plate bending method. shot peening was performed by steel shot intensity 0.15A-0.74A to annealed medium carbon steel specimens. Residual stress was measured by x-ray window process. The distributions of residual stress are all C type, which has the maximum stress at peened surface. Relaxation of residual stress distribution appeared exceedingly by small stress amplitude under fatigue test.
