Computational Mechanics Scientist Postdoctoral Research Associate

Organization: Computational Mechanics & Materials
Work Location: Idaho Falls, ID
Looking for: An expert in constitutive modeling (not micromechanics of materials)

Please Apply Before: October 31, 2019 (Midnight MDT)

In this position, you will work in the Computational Mechanics and Materials Department. Duties will include developing constitutive models for use in Bison and Grizzly, the nuclear fuel performance and component aging software packages under development in the Department. This development will occur using INL’s MOOSE computational framework (, a finite element-based platform for computational science research. Examples of modeling experience that are of interest include: concrete, particularly issues associated with performance degradation; metals, including anisotropic creep, high temperature creep, and general nonlinear response; and oxidation. While the focus of the research will be on constitutive model development, a significant effort will also be placed on analysis using the developed models. Furthermore, you will utilize other skills associated with the development of nonlinear solid mechanics software. Expectations include finding creative solutions to a wide range of challenges, providing software capabilities that are thorough, user-friendly, and well documented, working without the need for detailed direction, and developing a significant set of internal and external professional contacts.

You will support representation of the Department to sponsors and peers through programmatic and technical presentations and scientific publications; by enhancing technical currency and proficiency through peer participation and technical publication; and by writing technical manuscripts reporting progress, documentation, methods, and results from projects. It is expected that the work will result in publications in peer reviewed journals.

You will support identification of new research opportunities that attract funding, plays a key role in technical teams to respond to those opportunities, supports proposal writing activities by way of introducing new ideas and approaches, and helps secure funding for the conduct of that research.

You are expected to be a strong asset to our mature high-energy R&D team and work effectively both in isolation and as a team member. You must take direction from other team members and peers and also provide input in a constructive manner to others while maintaining positive and professional relationships.

You will maintain required training commensurate with security, safety, and work execution programs.


 PhD in Civil Engineering, Mechanical Engineering, or related field within the previous 5 years.

  • Demonstrated oral and published written communication skills (in English).
  • Demonstrated ability to conceive and execute computational science research.
  • Knowledge of the finite element method, solid mechanics, and constitutive relationships.
  • Experience developing computational software.
  • Experience writing proposals.
  • Must be able to work in a culturally diverse environment.
  • Must be able to obtain and retain access to the software packages under development.

Special Requirements and/or Training:
Knowledge and experience in any of the following will be helpful: parallel programming, iterative solvers and preconditioning, numerical methods, nuclear fuel, heat transfer, and multiphysics coupling.

**Must enjoy working in a culturally diverse work environment.**
