Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
The postdoctoral associate will quantify the shear strength of monolithic ceramic materials as a function of temperature using experimental techniques and numerical modeling. Responsibilities include conducting hot hardness and indentation testing, developing finite element models, and publishing research findings in peer-reviewed journals.
Candidates must hold a PhD in Ceramic Engineering, Materials Science, or a related field earned within the last five years. The role requires experience in brittle materials, experimental contact mechanics, and the ability to obtain a DOE Q-Clearance.
Requisition Id 16887
Overview:
We are seeking a Postdoctoral Research Associate who will support the Ceramics and Ceramics Composites (CCC) Group within the Materials Science and Engineering Division (MSTD) at Oak Ridge National Laboratory (ORNL), and who will focus on ORNL's continued development of methods to quantify shear (yield) strength of monolithic ceramic materials as a function of temperature. You will use and help refine techniques developed at ORNL that estimate shear strength based on the brittle-to-ductile transition, hot hardness testing, spherical indentation, and other new pending methods. Additionally, you will develop/refine finite element and numerical analysis models to portray shear strength response as a function of temperature, and to attempt to ultimately reconcile those various experimentally measured responses.
