Coupled Analysis of Solidification and Stresses in Centrifugal Casting Process

Abstract

In this paper, equations describing the changes in temperature and stresses accompanied with solidification was developed based on thermomechanics. The finite element scheme for stress analysis as well as the temperature distribution were formulated, where a unified inelastic constitutive relationship capable of describing both elastic-viscoplastic solid and viscous liquid was employed. Examples of numerical calculation of temperature affected by solidification and stresses were presented for some practical cases of centrifugal casting process.
