Numerical Simulation of Thermal Stress of Shaped Casting Based on Rheological Model

Abstract

Abstract: In order to study the thermal stresses at the mushy zone, a three dimensional rheological model [H]-[H|N]-[N|S] including elastic, visco-elastic and visco-plastic elements was established, its algorithm and codes for finite element method were also developed. A FDM/FEM integrated analysis system of thermal stresses was built based on the integration of this procedure with thermal analysis by finite difference method. A steel sample casting with a hot spot was simulated in order to validate this system, and the calculated and experimental results were in good agreement.
