Numerical Simulation of Thermal Stress in Castings Using FDM/FEM Integrated Method

Abstract:

A numerical simulation system, which integrated FDM (Finite Difference Method) and FEM (Finite Element Method) and coupled temperature field and stress field, was established. This system was then validated by simulation of a stress frame casting. The calculated results are satisfactory and in good agreement with the theoretical analysis. As a practical application, a wave-guide casting was simulated. The stress evolution during casting solidification, residual stress and deformation are predicted.
