Abstract:

The paper deals with methodology of determination stresses in a solidifying semi-solid medium. Finite Element Method is used for numerical solution of the problem. The kinetics of the solidification on the level of grain in the micro structure is taken into account to change the geometry of the finite element mesh. The calculated stresses are utilized to assess susceptibility of castings to hot tearing. It is achieved by formulating the local coefficient.
