Controlling flexural waves in semi-infinite platonic crystals
Stewart G. Haslinger, Natasha V. Movchan, Alexander B. Movchan +2
We address the problem of scattering and transmission of a plane flexural wave through a semi-infinite array of point scatterers/resonators, which take a variety of physically inte…
Tilted resonators in a triangular elastic lattice: chirality, Bloch waves and negative refraction
Domenico Tallarico, Natalia V. Movchan, Alexander B. Movchan +1
We consider a vibrating triangular mass-truss lattice whose unit cell contains a resonator of a triangular shape. The resonators are connected to the triangular lattice by trusses.…
Dispersion degeneracies and standing modes in flexural waves supported by Rayleigh beam structures
A. Piccolroaz, A. B. Movchan, L. Cabras
The paper presents a novel analysis of Floquet-Bloch flexural waves in a periodic lattice-like structure consisting of flexural beam ligaments. A special feature of this structure…
Spider-Web Inspired Mechanical Metamaterials
Marco Miniaci, Anastasiia Krushynska, Alexander B. Movchan +2
Spider silk is a remarkable example of bio-material with superior mechanical characteristics. Its multilevel structural organization of dragline and viscid silk leads to unusual an…
Eigenvalue problem in a solid with many inclusions: asymptotic analysis
V. G. Maz'ya, A. B. Movchan, M. J. Nieves
We construct the asymptotic approximation to the first eigenvalue and corresponding eigensolution of Laplace's operator inside a domain containing a cloud of small rigid inclusions…
Propagation and filtering of elastic and electromagnetic waves in piezoelectric composite structures
Domenico Tallarico, Natalia V. Movchan, Alexander B. Movchan +1
In this article we discuss the modelling of elastic and electromagnetic wave propagation through one- and two-dimensional structured piezoelectric solids. Dispersion and the effect…
