What Your Job Will Be Like:  We are seeking a Research & Development Postdoctoral Appointee to join a dynamic group of material and failure modeling researchers developing novel constitutive model calibration techniques. This is a multidisciplinary effort looking at the intersection of solid mechanics modeling, experimental characterization, optimization, and uncertainty quantification. To accomplish this task, the candidate will join a diverse team, working in the fields of constitutive model development (especially for nonlinear metal plasticity), surrogate model development, forward and inverse formulations in computational solid mechanics, and experimental material characterization (especially with digital image correlation). The project goal is to interlace advanced model calibration with material characterization methods, in order to actively drive an experiment to loading regimes that will improve model calibration and reduce model parameter uncertainty. In this role, you will have access to high- performance computing resources, advanced optimization and uncertainty quantification codes, tailored finite-element analysis software bundled with a wide array of additional computational simulation packages, and an advanced material characterization laboratory including a multi-axial load frame and digital image correlation equipment.

On any given day, you may be called on to:

  • Work with the mentorship of Sandia staff to perform world-class research focused on constitutive model related surrogate model development, Bayesian calibration, uncertainty quantification, and experimental material characterization

  • Develop novel calibration approaches fusing data from advanced full field diagnostics into a variety of novel simulation paradigms, combining elements of surrogate and finite element modeling

  • Publish and present results to the scientific community through technical conferences and peer- reviewed journals.

  • Develop laboratory-wide collaborations across multiple Sandia organizations and work as part of a multi-disciplinary team

  • Perform all duties in compliance with operational safety, security and quality guidelines. Join our team and achieve your dreams while making a difference!

Qualifications We Require:

  • PhD in Mechanical Engineering, Aerospace Engineering, Theoretical and Applied Mechanics, Civil Engineering, Applied Mathematics, Statistics, or closely related field. PhD required to start.
  • Demonstrated capability to conduct independent research and communicate results to the wider scientific community through technical publications and presentations.
  • Ability to obtain and maintain a DOE Q clearance.

Qualifications We Desire:

  • Expertise of surrogate model development, especially in the area of solid mechanics and constitutive modeling
  • Experience with Bayesian calibration and/or optimal experimental design
  • Familiarity with uncertainty quantification (e.g. forward uncertainty propagation, inverse problems, Bayesian methods, sensitivity analyses)
  • Familiarity with computational solid mechanics, non-linear finite-element methods, and plasticity formulations
  • Skill in interfacing with high-performance computing resources
  • Experience or familiarity with dimension reduction for high-dimensional full-field data, such as principal component analysis or wavelet decomposition
  • Familiarity with full-field experimental capabilities (e.g. digital image correlation)
  • Ability to work in combined computational and experimental setting
  • Strong ability to work in a multi-disciplinary team setting

About Our Team: The Materials and Failure Modeling Department 1558 performs material mechanics R&D, develops advanced engineering models, and deploys state-of-the-art computational capabilities to enable physically credible prediction of material behavior and failure in support of Sandia’s mission. Focus areas of the department include adaptive material and failure models, robust computational material library covering events from aging to shock physics, effective model calibration methodologies, and quantification of margin and uncertainty of material models.

Position Information: This postdoctoral position is a temporary position for up to one year, which may be renewed at Sandia's discretion up to five additional years. The PhD must have been conferred within five years prior to employment. Individuals in postdoctoral positions may bid on regular Sandia positions as internal candidates, and in some cases may be converted to regular career positions during their term if warranted by ongoing operational needs, continuing availability of funds, and satisfactory job performance.

EEO: All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability, or veteran status and any other protected class under state or federal law.

Security Clearance: Sandia is required by DOE to conduct a pre-employment drug test and background review that includes checks of personal references, credit, law enforcement records, and employment/education verifications. Applicants for employment need to be able to obtain and maintain a DOE Q-level security clearance, which requires U.S. citizenship. If you hold more than one citizenship (i.e., of the U.S. and another country), your ability to obtain a security clearance may be impacted.

Applicants offered employment with Sandia are subject to a federal background investigation to meet the requirements for access to classified information or matter if the duties of the position require a DOE security clearance. Substance abuse or illegal drug use, falsification of information, criminal activity, serious misconduct or other indicators of untrustworthiness can cause a clearance to be denied or terminated by DOE, resulting in the inability to perform the duties assigned and subsequent termination of employment.
