Description

  • We are excited to offer an opportunity for a Postdoctoral Researcher with to develop constitutive models and computational methods to simulate solid materials under dynamic loading. This position is in the Atmospheric, Earth & Energy Division, Computational Geosciences Group, but will include work on a variety of materials systems, not limited to geomaterials.

Requirements

  • Ability to secure and maintain a U.S. DOE Q-level security clearance which requires U.S. citizenship.
  • Ph.D. in mechanical/civil/materials engineering, applied math, condensed matter physics, engineering mechanics, computer science or related field.
  • Experience in application or development of numerical methods for solid mechanics (e.g. FEM, MPM, SPH, ALE, hydrocodes, etc.)
  • Experience with programming /code development for scientific or engineering applications.
  • Self-driven with scientific curiosity and an enthusiasm for research.
  • Excellent verbal and written communication skills necessary to collaborate in a multidisciplinary team environment.
  • Performs other duties as assigned.
  • Qualifications We Desire:
  • Any of these would be useful, a candidate is not expected to have all of these qualifications
  • Experience with numerical methods for large-deformation solid mechanics
  • Experience with constitutive model development.
  • Knowledge of theory and experimental methods relevant to the dynamic response (shock loading) of materials.
  • Experience in C++/python, especially experience with large legacy code base or coding for GPU.
  • Experience with Linux systems and high-performance computing platforms.
  • Experience with optimization methods for parameterization of physics models.

Responsibilities

  • Analyze available experimental data and identify and/or develop suitable constitutive model forms to describe strength, damage, rate, and thermal effects in a variety of engineering materials.
  • Develop, adapt, refine, and evaluate numerical methods to mitigate mesh dependency associated with localization (e.g. brittle damage, thermal softening) in large-deformation numerical simulations (e.g. ALE, Eulerian hydrocodes, MPM)
  • Use numerical optimization methods to parameterize complex material models based on available (limited, noisy, variable) data and physical constraints.
  • Use mesoscale simulation to investigate the response of composite / heterogeneous materials under dynamic loading.
  • Conduct large-deformation solid mechanics simulations to validate model for dynamic material response against experimental data.
  • Interface with experimentalists from other research groups to accurately interpret experimental data and inform prioritization of new experiments to reduce modeling uncertainty.
  • Present original research in conferences and publish in peer-reviewed journals.
