| Abstract: | 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. |
