Opportunity Description

Modeling and Simulation for Power Transfer in Hybrid Composite Material Systems A research opportunity is available with the U.S Army Research Laboratory’s (ARL) Vehicle Technology Directorate (VTD), located at NASA Glenn Research Center in Cleveland, OH. VTD is seeking a postdoctoral graduate with a background in Computer Science, Engineering, or Physics. Initiate and advance modeling studies of next generation material systems for aerospace power transfer with an emphasis on vertical takeoff and landing (VTOL) aircraft such as rotorcraft. Develop validated predictive tools for hybrid material systems incorporating advanced composites and ceramics, of interest to replace high strength and durability steels (including, but not limited to hybrid composite gears and composite shafts [1,2]). This opportunity will include material modeling at multiple scales using a combination of commercial software packages, specialized software tools and material databases, and interfacing with onsite experimental research to improve predictive modeling of these material systems and devices. The research associate will have access to fundamental materials test and characterization facilities as well component test and other applied facilities to assist with the refinement and validation of modeling techniques. Of interest are material system responses such as internal and interfacial stress and strain, fatigue and damage mechanisms, thermal transport, and dynamic characteristics and behavior. This effort will develop improved simulation environments and advance the potential of a step change in power transfer material systems to replace conventional gears, bearings and shafts. Desired skills include: experience modeling laminar composites, anisotropic materials, and adhesive bonds, using Abaqus. Additionally, experience with gear and driveline specific codes such as Transmission 3D and Calyx is desired. Potential tasks include design optimization for future test articles and modeling test apparatus to support experimental testing. [1] R. F. Handschuh, K. E. LaBerge, S. DeLuca, and R.

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!
