Predictive beam-lattice reduction for higher-order topological modes in a 2D SSH phononic crystal
Eloi Perez Compte, Michele Brun, Giorgio Carta +3
We develop a mechanically faithful reduced model for a two-dimensional topological phononic crystal composed of rigid square masses connected by slender elastic ligaments. Exploiti…

Longitudinal-flexural wave mode conversion via periodically undulated waveguides with constant and graded profiles
Vinicius F. Dal Poggetto, Fabio Nistri, Nicola M. Pugno +3
Wave mode conversion allows to transform energy from one propagating wave type to another at a boundary where a change in material properties or geometry occurs. Converting longitu…
