Modeling and Simulations of Armor Ceramics
at ORAU Workforce Solutions

Date Posted: 8/2/2019

Opportunity Description

Title of Research Opportunity: Modeling and Simulations of Armor Ceramics: Atomistics to Mesoscale Microstructure Located at Aberdeen Proving Ground in Maryland, the U.S. Army Research Laboratory (ARL) is the Army's central laboratory. Its diverse assortment of unique facilities and dedicated workforce of government and private sector partners make up the largest source of world-class integrated research and analysis in the Army. Interdisciplinary research opportunities exist in materials modeling at length scales ranging from atomistics to mesoscale microstructures to support discoveries relating ceramic processing-structure-property relationships. These simulations seek to uncover fundamental mechanisms controlling microstructure evolution and mechanical response of armor ceramics to provide insights for future material design and predict performance. Areas of research include (1) thermodynamic modeling of grain boundary complexions; (2) elucidating the role of defects and grain boundary character on grain growth and mechanics; (3) mesoscale modeling of microstructure evolution and mechanics; (4) bridging simulation scales by incorporating microstructure effects into continuum performance models; (5) integrating material simulations with experiments; (6) developing virtual materials characterization techniques; and (7) quantifying variability and uncertainty of models. Our research is performed in collaboration with other computational and experimental teams within ARL and academia. Qualified candidates should be US Citizens and have received their PhD in Materials Science, Mechanical Engineering, Chemical Engineering, Physical Chemistry, Physics, or Mathematics. Keywords: Ceramics, Modeling, Simulation, Computational Materials Science, Atomistics, Mesoscale

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!
