| Abstract: | Exampled with a heat exchanger, which was used in engineering practice, subjected to both pressure and temperature cycles, the stress and fatigue analyses for this exchanger were carried out by using finite element technology. Based on the distribution of the stresses, the influence of cyclic pressure and temperature loads on the tubesheet was analyzed. |
