Non-destructive estimation of 3D residual stress for peened materials using X-ray diffraction and eigenstrain theory

Non-destructive estimation of 3D residual stress for peened materials using X-ray diffraction and eigenstrain theory

Residual stresses generated by machining operations affect the dimensional accuracy and fatigue strength. However, fatigue strength can be improved by applying compressive residual stress through surface modification such as peening and carburising. If the three-dimensional residual stress of variou...
