Nonlinear Acoustics Transversal Axis
Nonlinear Acoustics Transversal Axis
Nonlinear Acoustics Axis
Coordinated by Georgios Theocharis
The Nonlinear Acoustics transversal axis aims to integrate and promote research across the laboratory’s three teams by bringing together a community of approximately twenty permanent researchers and faculty members, thereby fostering internal and cross-disciplinary collaborations. It serves as a platform for sharing knowledge and tools, coordinating responses to calls for projects, and facilitating exchanges through bibliographic monitoring, mini-workshops, and internal training sessions for doctoral students and permanent staff.
This axis plays a central role in structuring the laboratory's nonlinear research, focusing on six key themes:
-
Nonlinear Mechanical Metamaterials: Investigating the propagation of nonlinear waves, dynamic control of flexible metamaterials, and the emergence of nonlinear topological edge modes.
-
High-Amplitude Sound Propagation in Air-Filled Waveguides: Analyzing the effects of acoustic nonlinearities, fluid dynamics, dispersion, and the formation of shock waves and acoustic solitons.
-
Bifurcations and Nonlinear Vibrations of Elastic Structures: Studying the onset of buckling, instability, and periodic solutions in nonlinear elastic structures.
-
Nonlinear Phenomena in Musical Acoustics: Exploring the role of nonlinearity in sound production by musical instruments, and developing numerical and experimental methods for bifurcation analysis across diverse dynamical systems.
-
Non-Destructive Material Characterization Using Nonlinear Methods: Advancing techniques for assessing material properties through nonlinear acoustic signals for improved non-destructive evaluation.
-
Transducer Nonlinearities: Developing theoretical models, measurement techniques, and advanced signal processing methods for controlling transducer nonlinearities.
