Implication

Analysis demonstrates mechanical degradation in nitrile-butadiene rubber seals, indicating new model-switching guidelines.

Key Points

  • A degradation map was developed that aids in selecting the appropriate hyperelastic model for rubber seals.
  • The Neo-Hookean model excels in less-embrittled conditions, whereas the Mooney-Rivlin model is advised for advanced embrittlement.
  • Accelerated thermal aging tests were utilized to understand the mechanical degradation of nitrile-butadiene rubber seals.
  • The framework allows for enhanced stress-prediction accuracy while adapting to the evolving aging state.
