| Abstract: | The nonlinearity of the gasket material was simulated and the effect of external bending moments on gasket stress distribution, bolt loads and flange rotation was studied in this paper. The results of FEA were also compared with those of PVRC experiments. The results show that the finite element method has certain reliability. Upon gasket stress, this paper presents the relation between the joint tightness and external bending moments. |
