| Abstract: | In order to calculate thermal interface stress,interaction of two-layer slab and interface restrain impaction of two- layer deformation are analyzed.Based on Goodman model,tangent restrain module and normal restrain module are used for simulating constraints between two-layer slab.The balanced differential equation has been deduced by virtue of energy varia- tion principle.The computation method of interface force has been proposed. |
