Abstract

This paper presents numerical simulations for the prediction of thermal-stress and deformation fields resulting from phase change in solidifying bodies employing new finite element representations. The formulations demonstrated provide different perspectives and physical interpretation for the modeling/analysis of thermomechanical problems and possess several inherent advantages. In comparison to traditional approaches for solving similar problems, the paper employs new flux/stress based representations to enhance the overall effectiveness. Comparative numerical applications validate the applicability of the formulations for predicting the temperature-induced deformations and stresses resulting from effects due to phase change.
