| Abstract: | Coupling temperature,phase transformation and stress field,the process of local heat treatment for the piston rod of Shuikou power station to eliminate residual stress after welding and the failure analysis for the tense screw of Xiaolangdi station were simulated with three dimensional finite element method (FEM).The results show that the simulations are effective and can be used in the practices to solve the problems. |
