Date Posted: 9/10/2019

Opportunity Description

Tribological Modeling of Material Degradation Under Loss-of-Oil Conditions A research opportunity is available with the U.S Army Research Laboratory’s (ARL) Vehicle Technology Directorate (VTD), located at Aberdeen Proving Ground, MD. VTD is seeking a postdoctoral graduate with a background in Engineering, Physics, Chemistry, Material Science, or similar Physical Science Computational modeling and simulation studies are sought on physical and chemical failure mechanisms in high speed high load contacts under starved lubrication scenarios. A multidisciplinary modeling approach will combine different stages of failure such as behavior of the starved elastohydrodynamic lubricating film, surface chemistry of lubricant additives during mixed and boundary lubrication, initial stages of scuffing and oxidative wear, and continuum wear modes. Multiscale material modeling approaches, conjugate heat transfer models, multiphase computational fluid dynamics, molecular dynamics, ab initio chemical models are examples of multidisciplinary methods that may be used. Coordination of and integration with research conducted by government and university partners will be expected. The goal is to better understand experimental observations and develop predictive tools for improved operation of helicopter and ground vehicle drive system components (gears, bearings, transmissions) under loss-of-oil conditions with a focus on improving vehicle survivability.

About Us

Grooming future leaders in science and technology requires enhancing the skills, knowledge and experience of workers early in their careers. To that end, ORAU (Oak Ridge Associated Universities) assists in connecting the best and most diverse students, recent graduates, faculty and professionals with world-class fellowships, internships and jobs, whether in national laboratories, research institutions, federal government offices or private sector R&D departments.

ORAU works with agencies such as the U.S. Army Research Laboratory (ARL) Research Associateship Program (RAP) allow Postdoctoral Fellows, Journeyman Fellows (undergraduate and graduates students and recent graduates), Senior Researchers, and Summer Faculty engage in research initiatives of their own choice, that are compatible with the interests of the government and will potentially contribute to the general effort of the ARL. We work with the Environmental Protection Agency (EPA) to place recent graduates in full-time and part-time jobs in the Office of Research and Development at EPA under the National Student Services Contract. ORAU also works with Center for Medicare and Medicaid Innovation.

Research opportunities include, but are not limited to the following disciplines: Aerospace Engineering, Anthropology, Archeology, Biology, Biochemistry, Biological Engineering, Biomechanical Engineering, Biomedical Engineering, Chemical Engineering, Chemistry, Computer Science, Computer Engineering, Data Science, Electrical Engineering, Environmental Health Risk Assessment, Environmental Science, Entomology, Epidemiology, Ergonomics, Geology, Health Education Mechanical Engineering, Materials Science, Mathematics, Nanotechnology, Photonics, Physics, Public Health Economics, Public Health Policy, Toxicology, and more.

If you are ready to take the next step in your career path, then we are ready to help you!
