| Abstract |
A kind of hybrid numerical method between a finite volume method (FVM) and a finite element method (FEM) is applied for thermal stress analysis in a two-dimensional solidification of a pure metal allowing natural convection in the melt and volume contraction due to solid-liquid density change. A hypoelastic-viscoplastic constitutive model and a rate form of the principle of virtual work are involved to model the stress and deformation. Stable numerical solutions are obtained for the solidification process with solid-liquid density change and natural convection in the melt. Thermal stress distributions in a solidifying body are presented and discussed. |
