摘要
考虑工程中的非稳态温度场和热应力场问题，先后将空间域和时间域离散，从变分原理和伽辽金法导出非稳态温度场和热应力场的有限元计算式，对工程中的一个轴对称问题进行了分析。
The unsteady temperature fields and thermal stress fields are considered. The region of the consideration is divided into a number of subregions or elements. The finite element equations of temperature fields and thermal stress fields are derived by the variational principles and Galerkin method. An axisymmetric problem in engineering is analyzed.
