Existence of defects (such as cracks, pores, inclusions etc.) in steel structures is nearly unavoidable and therefore,
investigations on their behaviour and the structural integrity of the structure are necessary. Additionally, it is observed that
such defects can interact with corrosion pits, which are important consequences of the other phenomenon related to steel
structures. Therefore, this paper is devoted to a study on the influence of the corrosion pit on fatigue crack propagation
under mixed-mode I/II loading conditions. A rectangular bar subjected to remote tensile loading is modelled numerically
by means of the finite element method and principles of the linear elastic fracture mechanics are applied. Several
conclusions are stated on the effect of individual parameters varied within the study on the crack propagation. More
extensive studies are intended in the field of crack deflection etc.
