An analytical method to estimate the temperature and stress distribution in an ingot due to a steady vertical semicontinuous direct chill casting process in a spatial coordinate system is presented in this paper. The interaction between temperature and phase change is carefully discussed to obtain the heat conduction equation including latent heat generation with the consideration of material flow. A viscoplastic constitutive relationship capable of describing the viscoplastic solid as well as viscous fluid is employed for stress analysis. As an example of the simulation, a casting process for axisymmetric aluminum ingot is examined by use of the finite element method, and the calculated results of temperature, deformation and stress are revealed to simulate the actual behavior during semicontinuous direct chill casting process.
