Phenomenon of corrosion in structural materials is very important, because they very often yield to aggressive environment. Moreover, not inconsiderable effect of fatigue damage via cyclic loading of such engineering structures should be considered as well. Thus, the influence of a corrosion pit (of a circular segment shape) on the stress distribution in a rectangular specimen subjected to remote tensile stress range has been investigated via finite element method. Particularly the stress concentration factor has been calculated for various sizes of the corrosion pit and the results obtained have been discussed.
