For technology called to function under harsh temperature swings, e.g. satellite antennas, thermal expansion can be an enemy to fight against. But for others, e.g. deployable systems, thermal expansion can become even an ally to work with. In this seminar, I will contribute to address challenges currently existing on both fronts through the lens of metamaterials mechanics: i) how to control thermal responses in ultralightweight lattices called to meet strict directional requirements of thermal expansion, ii) how to engage temperature in morphing materials that need to deploy in situ under extreme temperature conditions. The approach that I will follow draws from concepts of mechanics, geometry, materials, and structural optimization, and I will resort to a combination of theory, computations and mechanical testing for performance validation.


Damiano Pasini is the Louis-Ho Faculty Scholar of the Faculty of Engineering at McGill University and Professor of Mechanical Engineering. His research interests lie in solid mechanics, advanced materials and structural optimization with current focus on mechanical metamaterials. He is fully engaged in understanding their mechanics, introducing reliable predictive models, and using them to design, optimize, build and test architected materials with tuned functional properties that are of practical use in aerospace and beyond.
