Postdoctoral Researcher - Microstructural Modeling and Characterization of High-temperature Ceramics

Requisition Id14543

Overview:

We are seeking a Postdoc who will focus on microstructural characterizations of nuclear ceramics and mechanistic modeling of the material degradation behavior under nuclear reactor relevant environments. This position resides in the Nuclear Energy Materials Microanalysis in the Materials in Extremes section, MSTD, PSD, at Oak Ridge National Laboratory (ORNL).

The Postdoctoral Research Associate will contribute to the development of novel modeling and characterization frameworks that will be based on 1) simulation or characterization of the microstructures of ceramics using 3D characterization techniques, 2) establishing connections between material structure and mechanical properties, 3) predicting the behavior of ceramics under extreme environments. Moreover, the candidate will contribute to the constitutive modeling frameworks and develop image-based models for high-temperature ceramics. Knowledge and experience of relevant characterization techniques, including x-ray computed tomography, scanning electron microscopy, or other microscopy 3D techniques, is desirable. These modeling and microscopy approaches will be combined with experimental data to evaluate various ceramic materials. Demonstrated experience in implementing nonlinear constitutive models in commercial finite element (FE) codes is desirable. You will be expected to collaborate with research staff and industry partners focused on material research and development through computational modeling and multimodal characterization.
