Title: Topological metamaterials: emerging trends in manipulating mechanical waves

Date and Time: 3rd December 2019, 4pm

Venue: Auditorium, Department of Aerospace Engineering

Abstract: Due to the recent discovery of topological insulators in condensed matter physics, a new notion of topology has emerged in association with the intrinsic wave dispersion of a structure. Consequently, certain topological invariants can be used to characterize the dispersion, and intrinsic robustness linked to them manifests as a defect-immune vibration response of the system. In this presentation, I will talk about our recent studies on 1D, 2D and 3D structures showing unprecedented wave phenomena, thus potentially offering novel ways to robustly manipulating mechanical waves for applications in energy harvesting, vibration isolation, and structure health monitoring.

Speaker Biography: Dr. Rajesh Chaunsali, earned his doctorate in 2018 from the University of Washington, Seattle, USA, in the Department of Aeronautics and Astronautics. He received his Bachelor’s and Master’s degrees in mechanical engineering from the Indian Institute of Technology Madras in 2012. He worked at General Electric Aviation during 2012–14, where he designed composite fan blades for turbofan engines. Rajesh’s research lies at the intersection of physics and engineering, where he is broadly interested in understanding and controlling the flow of mechanical energy in materials and structures. He has been a recipient of several fellowships, travel and teaching awards. He has authored 15 peer-reviewed papers in prestigious journals, such as Physical Review Letters, Journal of Mechanics and Physics of Solids, Advanced Materials, and Scientific Reports.

All are welcome
