Abstract Graphite gaskets are widely used static seals. This study examines the mechanical properties on the seal interface which is significant to the sealing performance. The study uses finite element simulations based on a test rig structure and elastic-plastic material properties. The compression-resilience curve is measured in the same test rig. The simulations show the changes in the contact pressure and deformation distribution during loading and unloading. The simulated compression-resilience curves agree with the measured data to validate the finite element model. The results explain the sealing mechanism of high contact stiffness, load stability, and installation repeatability for this kind of gasket.
