| Abstract: | In the present paper,the autofrettage residual stress relaxation of the high pressure tubular reactor in homogeneous temperature field is studied theoretically.A theoretical model of remaining autofrettage residual stress in homogeneous temperature field is developed based on creep theory and the theory of elastic mechanics of metal materials.The calculated results by means of the model are in excellent agreement with the experimental ones. |
