The large-scale cast steel products have been used in broad fields, such as industrial machine, power generation, construction, vessels, and automobiles. In chill casting of cast steel uneven cooling rates at different regions of the large-scale cast steel generate thermal stress, which cause solidification cracks. The process of solidification process is complex in nature and the simulation of such process is required in industries before it is actually undertaken. In this study, a three dimensional thermal elast-plastic stress analysis has been preformed by using finite element method in connection with three dimensional non-steady state heat transfer analysis, including interaction between the temperature and stress field. The results provide further understanding of the observed solidification crack failure for large-scale cast steel.
