| Abstract: | Based on a transient temperature distribution of finite length thick wall tube, which is obtained by solving the governing equations with phase transformation, shape coefficients and subcooling boiling boundary conditions considered, the increment form of thermal elastoplastic constitutive equation is derived and solved by means of Finite Element Method. The transient thermal stresses and residual stresses are obtained and the influencing factors on the thermal stresses are analyzed and discussed. |
