| 1 | Numerical Simulation of Thermal Stress of Shaped Casting Based on Rheological Model显示文摘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 al gorithm 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 simu lated in order to validate this system, and the calculated and experimental results were in good | Kang, JW Liu, BC Xiong, SM | 1999 | Journal of Materials Science & Technology1999，15，3： | 6 |
