| Abstract: | In this paper, the thermo-elastic-plastic field of a marine boiler drum is analyzed by using FEM, and diagrams of three-dimensional stress and deformation are given. The finite element calculation was carried out at twice for the region of stress concentration. The numerical results are of significance for analyzing the damages of boiler drum. |
