Advances Toward Life Estimation in Static Sealing

Life estimation for complex systems ultimately involves a suite of models for the various potential product failure modes. The advances in gasket test and analysis techniques presented in this paper lay the foundation for development of this future predictive capability. Static sealing performance factors of creep-relaxation, fatigue resistance, and leak rate are three principal determinants of application sealing success. This paper explores progress in each of these areas and presents concepts needed to integrate them into a coherent, probabilistic methodology.
