Special, hexahedral 21- and 28-node isoparametric nite elements have been employed to model the contact zone. In this model, one takes into account loading due to the working pressure in the gap between the gasket and the ange arising as an e ect of the progressing joint opening, what has not been considered in recent papers. Nonlinear sti ness characteristics of the bolt and the ange with the gasket are developed. Working pressure corresponding to the critical bolt force resulting in the joint leakage (complete opening between the gasket and the ange) is determined. FE computational results are compared with the available experimental results. The numerical results are presented using the authors’ own graphical postprocessor. 1. Subject of analysis Flange joints are commonly used, e.g. in pipeline connections. Various aspects concerning approximate analytical calculations in a one-dimensional form, properties and servicing of the bolt joints are described in [1,2,3]. Osgood [4], Motosh [5], Shigly and Mischke [6] discussed in their works the ange connections in which the contact surfaces, which include the area between the anges and the gasket, are assumed to be constant and without friction between the ange and the gasket. The nonlinear force-de ection behaviour of the connection was presented in Junker [7] and Bickford [8]. In the papers by Zahavi and others [9,10,11], one can nd numerical analyses based on the nite element method that make use of commercial nite eleMaritime University of Szczecin, Division of Computer M
