| Abstract: | In this paper,the rheofogical model is proposed with the experimental investigation of the semisolid rheologieal behavior of Al- Si alloy and hence the stress-strain mathematical equation during solidifieation processes of Al-Si alloy castings is developed. Therefore,a reliable mathematical model is provided for nu-merical simutation of resluual stress and prediction of hot cracking during solldifica-tion process of Al-Si allOy castings. |
