Bio-inspired seismic metamaterials: Time domain simulations in transformed crystals
Ronald Aznavourian, Tania Puvirajesinghe, Stephane Brule +2
We introduce the concept of transformation crystallography which consists of the application of geometric transforms to periodic structures. We consider motifs with three-fold, fou…
Control of Rayleigh-like waves in thick plate Willis metamaterials
Andre Diatta, Younes Achaoui, Stéphane Brûlé +2
We explore interactions of elastic waves propagating in plates (with soil parameters) structured with concrete pillars buried in the soil. Pillars are 2 m in diameter, 30 m in dept…
Flat lens for seismic waves
Stephane Brule, Stefan Enoch, Sebastien Guenneau
A prerequisite for achieving seismic invisibility is to demonstrate the ability of civil engineers to control seismic waves with artificially structured soils. We carry out large-s…
Seismic waves damping with arrays of inertial resonators
Younes Achaoui, Bogdan Ungureanu, Stefan Enoch +2
We investigate the elastic stop band properties of a theoretical cubic array of iron spheres connected to a bulk of concrete via iron or rubber ligaments. Each sphere can move free…
