Dynamic Response of Structural Material Fabricated
at ORAU Workforce Solutions

Date Posted: 4/23/2019

Opportunity Description

Dynamic Response of Structural Material Fabricated by Additive Manufacturing Structures with radically improved performance and novel functionality have not been realized because they often require material property sets that are competing such as yield strength and ductility, hardness and density, and stiffness and toughness. The capability to realize structures that would surmount these barriers has been demonstrated separately by nature or in selected polymer-based systems, by advanced modeling results, and by experiments that span the nano- to the micro-scales. Fused deposition modeling (FDM) additive manufacturing is being employed by ARL researchers to realize advanced logical structures characterized by lightweight with superior durability and energy absorption. A research opportunity exists for a Materials Engineer with experience in fracture analysis to experimentally characterize the dynamic response of polymer material specimens fabricated using FDM additive manufacturing. The research objective is to gain better understanding of dynamic behavior to establish constitutive relationships useful in the modeling of the beneficial aspects of energy absorption for components fabricated by FDM. The specific research objectives will be accomplished by performing high strain rate deformation and dynamic failure characterization of advanced polymers for experimental and computational studies to enable additive manufacturing of advanced structural components that exhibit unique characteristics such as pseudo-ductility, graceful collapse, and 'fatigue-free' characteristics.

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!
