About this position
Oak Ridge National Laboratory is seeking a Postdoctoral Research Associate in Computational Solid Mechanics for Digital Certification and Qualification in Knoxville, Tennessee. The position is based in the Deposition Science and Technology Group within the Manufacturing Science Division of ORNL’s Energy Science and Technology Directorate.
The research centers on multiscale modeling and simulation for probabilistic lifing of high-temperature alloys and structural materials used in extreme environments. The postdoctoral researcher will investigate the mechanical behavior of materials and contribute to computational frameworks that support the certification and qualification of components produced through advanced manufacturing processes.
Core research activities include developing and implementing nonlinear constitutive models in commercial or open-source finite element codes, including platforms such as Abaqus, ANSYS, MOOSE, and DAMASK. The researcher will also work on crystal-plasticity constitutive models for additively manufactured alloys and apply multiscale approaches to fatigue, ductile fracture, and probabilistic component-life assessment.
The role offers a multidisciplinary research environment involving computational scientists, experimentalists, engineers, and collaborators from industry. Work will connect materials science, mechanical engineering, computational mechanics, heat transfer, additive manufacturing, and digital certification. The researcher will present findings at workshops and conferences, publish results in peer-reviewed journals, contribute to proposal development, and collaborate with research staff and industry partners on basic and applied research aligned with ORNL’s national laboratory mission.
The appointment is located at Oak Ridge National Laboratory, a U.S. Department of Energy Office of Science national laboratory with a large research community addressing energy, environmental, and security challenges.
