| Abstract: | In view of the factors such as the srain-hardening property of tube and tubesheet materials,the effects of adjacent tubesheet hoes on the expanded tube ,a 3-D nonlinear finite element model of the hydraulically expanded joint is established for E-3201 heat exchanger .By solving this model ,the contact stress, the distribution of residual contact stress and the influence of expansion pressure on the distribution can be described. It provides theoretical basis for the structure design and the optimal process parameter of hydraulically expanded joints. |
