About the role
AI summarisedA*STAR's AMS Division, IHPC, is seeking a highly motivated Research Scientist to join a multi-disciplinary team. This role involves joint laboratory research with an Oil&Gas company, focusing on developing computational models and enhancing the long-term reliability of polymeric seals used in mechanically energized sealing systems for oil and gas applications.
ResearchOnsite
Key Responsibilities
- Develop finite element (FE) models of mechanically energized sealing systems to evaluate performance and reliability under thermal, mechanical, and environmental loads.
- Automate FE-based parametric studies and perform sensitivity analyses to identify critical material and geometric factors affecting seal performance.
- Investigate failure modes such as viscoelastic relaxation, thermal aging, and thermal cycling; develop and validate degradation models for these mechanisms.
- Integrate degradation models with traditional metrics (e.g., compressive stress relaxation, mechanical property evolution) for performance prediction.
- Collaborate with experimental teams and industry partners to refine test procedures, define reliability criteria, and assess lifecycle failure risks.
Requirements
- PhD in Mechanical Engineering, Materials Science, Applied Physics, or a related field.
- Solid background in continuum mechanics and polymer material behavior (especially aging and viscoelasticity).
- Strong foundation in finite element modelling (FEM).
- Proficiency in FE software, specifically Abaqus.
- Experience with Python scripting for automation and parametric studies.
- Proficiency in scientific programming languages (Python, Fortran, MATLAB, or similar).
- Proven ability to work independently, meet deadlines, and produce high-quality technical reports.
