Abstract
A method for estimating a seal of a gasket, including: digitally simulating, using a computer, a creep deformation of a gasket resulting from crushing of the gasket between two bearing surfaces; calculating, at an interface between the gasket and one of the two bearing surfaces and during the computer simulation, a cumulative plastic deformation of the gasket, an axial stress between the gasket and the one the two bearing surfaces, and a contact length between the gasket and the one of the two bearing surfaces; and calculating a simulated porosity filling coefficient, representing the seal of the gasket at the interface.
