Abstract

EDITOR’S RECOMMENDATIONS Theoretically, cast steel is ideally suited for use in structures subject to fatigue loads due to its high mechanical strength and virtually free shaping possibilities. However, the component resistance is determined by manufacturing-related im- perfections. Due to a lack of knowledge and the absence of easily applicable de- sign approaches, the use of cast steel components is usually rejected or coun- tered by the highest demands on manu- Fracture surfaces with blended crack fronts of the numerical calculations for differently distinct casting facturing quality. This blanket choice is defects usually uneconomical and not necessary from a technical point of view, since even major casting defects do not necessarily tance categories.
