Abstract: The alternating stop-band characteristics of periodic structures have been widely used for narrow band vibration control applications. The objective of this work is to extend this idea for broadband excitations. Toward ...

Abstract: This paper investigates the flexural wave propagation through elastically coupled telescopic metabeams. It is assumed that the metabeam is formed by connecting successive beams with each other using distributed elastic ...

Abstract: This work proposes a unique configuration of a two-dimensional metamaterial lattice grid comprising curved and tapered beams. The propagation of elastic waves in the structure is analyzed using the dynamic stiffness matrix ...

Abstract: The vibration and sound radiation characteristics of a double leaf panel wall with corrugated core are analyzed. The core comprises of repeating unit cells along the length of the panel. Each cell is a combination of a ...
