Dynamical Metamaterials

Metamaterials with tunable dynamical properties (TU/e)

Metamaterials with tunable dynamical properties (TU/e)

Presentation (Pdf file, 2 MB) held by dr. Varvara Kouznetsova at the Kick-off Symposium 'Dutch Materials 2015', 6 October 2015.


Metamaterials, Nonlinear Dynamics, Local Resonance, Wave Propagation, Hyperelasticity, Energy Exchange, Computational Homogenization, Multiple Scales



The development of metamaterials enables to engineer materials with extraordinary features, beyond the traditional limits. In the linear dynamic regime, metamaterials have already enabled a wide range of new functionalities, such as cloaking, super-lenses, and signal filtering. The consideration of nonlinearity has the potential to bring a myriad of new opportunities for metamaterials. Within the 4TU.High-Tech Materials research program, we are developing metamaterials with nonlinear resonant inclusions. Results of this research show emergent dynamic features which may enable tunability, new mechanisms of sound and vibration attenuation, and the realization of a “mechanical diode”. Besides, efficient computational schemes are being developed for optimal analysis of the emergent metastructure design.

Short Biography Priscilla BrandĂŁo Silva

Born in Rio de Janeiro, Brazil, Priscilla has always been curious and passionate about Science and Technology.

Priscilla got the Bachelor degree in Mechanical Engineering at the University of Campinas, Brazil. For being the best student among mechanical engineering undergraduates in 2010, she was awarded the Merit Diploma by the Institute of Engineering in Brazil. In 2015, she got the Ph.D. degree at the University of Campinas (Brazil) being advised by Prof. José Roberto de F. Arruda and Prof. Jean-Mathieu Mencik. In her thesis, she contributed to the development of a numerical technique for the computation of the dynamic response of structures involving periodic components using a wave-based approach. During her thesis, she did research internships at the University of Auckland, in New Zealand, where she collaborated with Prof. Brian Mace, and at INSA Centre Val de Loire, in France, with Prof. Jean-Mathieu Mencik, her co-advisor. Her thesis was awarded the best thesis in 2015 of the Faculty of Mechanical Engineering at the University of Campinas, Brazil.

After her Ph.D., she became Assistant Professor in the Department of Mechanical Engineering at the Federal University of CearĂĄ, in Brazil. Her passion to contribute to the society with the development of new technologies led her to a new challenge and full-time research experience. Funded by the 4TU.High-Tech Materials research program, Priscilla is currently investigating a new generation of metamaterials by exploring the nonlinear dynamics of embedded microstructures at Eindhoven University of Technology (TU/e, The Netherlands). This research is conducted within the Mechanics of Materials group of TU/e with dr. Varvara Kouznetsova and Prof. Marc Geers, and in collaboration with Prof. Michael J. Leamy from Georgia Tech, USA.
