Claim Text:
1. A method for estimating tightness of a seal, comprising: performing, on a computer, digital simulation of a deformation by creep of the seal by compression of the seal between two surfaces; calculating, on the computer and at at least one interface between the seal and one of the two surfaces, of a cumulative plastic deformation p of the seal, of an axial stress Smzz between the seal and the one of the two surfaces, and of a contact length Lc between the seal and the one of the two surfaces, during the digital simulation; calculating, on the computer, a simulated pore plugging coefficient F where λ, α and β: coefficients with values that depend on the material of the seal, re and ri: respectively external radius and internal radius of the deformation of the seal, m, r: position along contact between the seal and the at least one of the two surfaces, Smzz: axial stress, MPa, σ p: cumulative plastic deformation, pmax: maximum value attained by p during the simulation, p
