Abstract

In this study, applied tensile plastic preload in 2024 and 7075 Al-alloys plates with central hole generate residual stress field. Around the central hole compressive residual stress was generated when finite element method was used and Von Mises criterion was applied for plastic preload. The level of compressive residual stress increase in increasing of applied plastic preload. Fatigue life and fatigue crack growth rate (FCGR) depend on the level of plastic preload. Consequently fatigue life increase and FCGR decrease. No high effect of level of applied plastic preload was shown for 7075 Al-alloy on fatigue behavior.
