A New Stress Criterion for Hot-Tearing Evaluation in Solidifying Casting

This work concerns a new criterion for hot-tearing evaluation in castings. Algorithm describing the conduction of computer simulations of phenomena accompanying the casting formation, which performing is the preparation stage for using of this criterion, is also described. According to the low recurrence of phenomena occurring during solidification (e.g. grained structure parameters, stresses distribution) the casting’s hot-tearing inclination can be estimated only in approximated manner. Because of still following at present rapid computer processors development, and techniques of its programming, enables to suppose that in short time the efficiency of computer simulations will arise so much, the problem of hot-tearing evaluation newly became interesting for the team working on computer simulations at the Institute for Computer and Information Sciences at Częstochowa University of Technology.
