摘要: 利用由金属物理学的基本概念导出的含一级相变非线性热传导方程,在微时段内线性化,由变物性线性化泛函,建立了金属凝固过程中温度场的有限元方程并对轴对称问题的金属凝固过程中的温度场作了数值模拟和测试。得出比较满意的结果。

Abstract: By using Linearization method in little time interval, from the heat conduition equation with the 1st-order phasetransformations, the foundation equations of Finite Elememts in solidifications of Metals is established in the paper. The numerical analog on symetric problem in solidification of a grayiron in sandform is obtained by means of triangular element, and the results tallies the corresponding test well.

Key words: finite element, phase transformation, solidifications
