| Outline of Final Research Achievements |
Indentation creep test was carried out using TMA with Berkovich indenter to evaluate the viscoelastic characteristics of sealing products. The time-temperature superposition principle was applied to obtain the master curve of the creep compliance of gasket material at elevated temperature. The elastic-viscoelastic correspondence principle was also applied to estimate the gasket creep strain in the flanges from the master curve of the creep compliance. Gasket creep strain rate can be predicted at an elevated temperature for a long term of 10 years. Estimation of the gasket creep strain rate in the flanges shows a good agreement with the experiment data.
