We develop a new asymptotic model of the dynamic interaction between an elastic structure and a system of gyroscopic spinners that make the overall multi-structure chiral. An important result is the derivation and analysis of effective chiral boundar... Read More about Vibrations and elastic waves in chiral multi-structures.

Design of a chiral elastic structure supporting interfacial waveforms (2018)
Journal Article
Nieves. (2018). Design of a chiral elastic structure supporting interfacial waveforms. https://doi.org/10.1109/MetaMaterials.2018.8534138

An infinite heterogeneous elastic triangular lattice connected to a non-uniform array of gyroscopic spinners is considered. An algorithm is described for generating interfacial waves that propagate along the boundaries of subdomains containing inhomo...

We present a novel physical model of a gyrobeam, an active chiral structural element where flexural and rotational motions are coupled. In the literature, the gyrobeam is described as a mathematical object possessing a continuous distribution of stor... Read More about Physical Model of a Chiral Flexural Waveguide.

We demonstrate a new method of achieving topologically protected states in an elastic hexagonal system of trusses by attaching gyroscopic spinners, which bring chirality to the system. Dispersive features of this medium are investigated in detail, an... Read More about Interfacial waveforms in chiral lattices with gyroscopic spinners.

Elastic Chiral Waveguides with Gyro-Hinges (2018)
Journal Article
Nieves. (2018). Elastic Chiral Waveguides with Gyro-Hinges. Quarterly Journal of Mechanics and Applied Mathematics, 157 - 185. https://doi.org/10.1093/qjmam/hby001

This article presents a novel chiral structure, consisting of Euler–Bernoulli beams connected to gyroscopic spinners. A new type of boundary condition is introduced, which is referred to as a gyro-hinge. In this system, flexural waves are coupled wit... Read More about Elastic Chiral Waveguides with Gyro-Hinges.
