Corrosion fatigue problem in ship structure and its calculation approaches

High strength materials on ship body are notable for their rigidity and resistance to a hostile environment. Nevertheless, if a stressed component is exposed to chemical attack, it may suffer from a form of delayed fracture known as static fatigue. From the point of view of a designer, it is clearly desirable to determine the behavior of sub-critical crack growth; the crack path and crack growth rate, as a function of material properties and loading conditions are of particular interest. This paper presents advances in stress assisted corrosion problem in history and its corresponding numerical approaches in last decades, and finally, comes up with consideration and crucial suggestions for future work.
