Thermo‐mechanical finite element model of casting systems

Abstract

Abstract A coupled finite element model is developed to simulate the metal casting process. We present a new method for capturing the solidification zone and obtaining the corresponding rate of phase change. The latent energy release is predicted by the heat conduction rate and introduced by following the enthalpy‐temperature curve. The influence of mould‐metal contact is considered in calculating the heat flux through the mould‐metal interface. A viscoplastic model is employed to predict the gap opening and evolution of plastification. Four examples are presented to demonstrate certain numerical aspects and the capability of the model for industrial applications.
