method for estimating the residual fatigue life of service damaged and corroded structural members are developed. Scratch and hit marks, misplaced or empty holes that are exposed to corrosion are considered. The method is based on Palmgren-Miner's damage accumulation rule and field registered stress collectives. Standard methods are used to take effects of stress concentration and corrosion into account. If stress concentration and corrosion combine as is usually assumed, then corroded scratch marks may affect residual life
