Original Abstract

Both corrosion and fatigue crack propagation are the most common phenomena degrading metal/steel structures. Therefore, an extensive study is performed on this topic. Namely, results of a numerical analysis made on 2D model of a rectangular specimen containing a corrosion pit near a short edge crack that is arbitrarily oriented towards the cyclic tensile loading. Thus, I+II mixed mode conditions are created and the behavior of the crack is investigated by means of the concept of the equivalent stress intensity factor range. Discussion on effect of various parameters (such as crack length, corrosion pit size, crack inclination angle) on fatigue crack propagation is presented and important conclusions, that can help in further numerical/experimental analyses, are summarized.
