Abstract: A new approach and relevant computer program for seal analysis are presented, which is applied to flange seal system of a nuclear reactor pressure vessel model. In this procedure, the seal analysis is treated as a 3-D coupled thermoelastoplastic contact problem and a new finite element solution based on step method is developed to sieve it. The numerical results of this application is in common with the experimental data.

Key words: Contact problem, Finite element method, Pressure vessel, Seal analysis
