Cornell professor to deliver engineering Graduate Seminar at Alfred University

ALFRED, NY— Mostafa Hassani, assistant professor in the Sibley School of Mechanical & Aerospace Engineering (MAE) and the Department of Materials Science and Engineering (MSE) at Cornell University, will deliver a Graduate Seminar for Alfred University’s Inamori School of Engineering on Thursday, Nov. 11, from 10:20 to 11:10 a.m.

The seminar, titled “In-Situ Studies of Materials under Extreme Conditions: From Mechanics to Manufacturing,” will be offered virtually, via Zoom.

Hassani earned his PhD degree in Mechanical Engineering from Politecnico di Milano. His research is focused on mechanical behavior of structural materials, metal additive manufacturing, and solid phase processing. He started his tenure track position in July 2021 after serving as a Senior Research Associate and Lecturer at Cornell. Prior to that, he was a Postdoctoral Associate in the Department of Materials Science and Engineering at the Massachusetts Institute of Technology.

Hassani says in the abstract for his seminar presentation: “The emergence of new materials with complex microstructures calls for a renewed understanding of the mechanical behavior, beyond the limited insight offered by the conventional post-deformation or post-failure characterizations. Recent advances in in-situ experimental mechanics across length scales have opened unique opportunities to elucidate material mechanisms and inform materials design. The first part of this talk surveys our recent real time studies with an emphasis on the understanding of the behavior of materials under extreme loading conditions. We cover in-situ measurements with scanning electron microscopes, high speed cameras, and synchrotron X-rays, and discuss severe plasticity, high rate mechanics, and failure in a number of structural materials. In the second part, we survey our work using an in-situ platform to study the physics of a solid-state additive manufacturing process, namely, cold spray. We discuss new insights on impact-induced bonding, powder particle size effect, and microstructural evolution at interfaces. We also propose processing windows by identifying the conditions for solid-state bonding, impact-induced melting and erosion.”
