The CORIA Center, directed by Professor Martin Byung-Guk Jun, held its first seminar in the CORIA Seminar Series. Professor Sangkee Min from University of Wisconsin–Madison delivered a presentation titled “Modeling Ductile-to-Brittle Transition in Ultra-Precision Machining of Single-Crystal Ceramics.” The event brought together faculty, researchers, and students to explore recent advances in ultra-precision manufacturing of advanced materials.

In the seminar, Professor Sangkee Min presented research on ultra-precision machining (UPM) of brittle single-crystal ceramics, addressing the challenge of crack initiation. He introduced a unified framework linking process parameters, cutting forces, stress evolution, and crack formation through a three-step modeling approach. Supported by experiments across different crystallographic orientations and enhanced by machine learning and stress analysis, the study enables accurate prediction of ductile-to-brittle transition behavior. The work provides a practical, physics-informed basis for optimizing machining conditions and achieving defect-free fabrication of complex ceramic components.

The seminar marked a strong start to the CORIA Seminar Series, highlighting the center’s commitment to sharing cutting-edge work and encouraging interdisciplinary collaboration. By bringing together scholars from universities and research institutes, it fosters meaningful connections that lead to joint projects, knowledge exchange, and long-term partnerships. These interactions are helping expand CORIA’s collaborative network and enhancing its impact across institutions.
