Influence of pitting corrosion on fatigue and corrosion fatigue of ship and offshore structures. Part II: Load - pit crack interaction

In the paper has been discussed influence of stresses on general corrosion rate and corrosion pit nucleation and growth rate, whose presence has been questioned by some authors but accepted by most of them. Influence of pit walls roughness on fatigue life of a plate suffering pit corrosion and presence of so called "non damaging" pits which never lead to initiation of fatigue crack, has been presented. Possibility of prediction of pit-to-crack transition moment by two different ways, i.e. considering pit as a stress concentrator or as an equivalent crack, has been analyzed. Also, influence of statisyical distribution of corrosion pits depth as well as anticorrosion protection on fatigue and corrosion fatigue of pitted elements, have been described.
