Metamaterials for wave propagation and vibration control

1 – Design of novel seismic isolation systems based on elastic metamaterial concepts.
Development of analytical and numerical models to study the dispersion and attenuation of seismic waves interacting with buried resonant structures. Design of small-scale experimental tests with distributed resonant systems embedded in homogenous and heterogeneous material. These tests aim at understanding the influence of complex soil stratigraphy on the dynamic behavior of buried resonant structures.

2 – Design of novel planar metamaterial systems for surface acoustic waves control.
Development of analytical and numerical models to understand the interaction of planar metamaterial systems, i.e., the metasurfaces, with SAWs and design of metasurfaces for filtering, waveguiding and lensing of SAWs.

3 – Development of numerical techniques  for the analysis of linear and dissipative phononic materials and resonant metamaterials.

 

Non Destructive Testing and Structural Health Monitoring

1 – Application of vibration-based structural health monitoring techniques to identify and locate anomalies in structures and infrastructures

2 – Development of numerical techniques for the dispersion analysis of guided waves in 1D and 2D strctural waveguides. Use of guided waves for damage detection in structural components.
