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.
