Coupled dynamics of chiral waves and gyroscopic systems with applications to atmospheric phenomena
Alessio Kandiah, Ian S. Jones, Natasha V. Movchan +1
The present paper introduces the notion of chiral gravitational elastic waves and explores their connections to equatorial and planetary waves. The analysis of the gravity-induced…
Vibrations and elastic waves in chiral multi-structures
Michael Nieves, Giorgio Carta, Ian Jones +2
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 impor…
Interfacial waveforms in chiral lattices with gyroscopic spinners
Marta Garau, Giorgio Carta, Michael Nieves +3
We demonstrate a new method of achieving topologically protected states in a discrete hexagonal lattice by attaching gyroscopic spinners, which bring chirality to the system. Dispe…
Semi-infinite herringbone waveguides in elastic plates
Stewart G Haslinger, Ian S Jones, Natasha V Movchan +1
The paper includes novel results for the scattering and localisation of a time-harmonic flexural wave by a semi-infinite herringbone waveguide of rigid pins embedded within an elas…
Active cloaking for clusters of pins in thin plates
Jane O'Neill, Ozgur Selsil, Stewart Haslinger +2
This paper considers active cloaking of a square array of evenly spaced pins in a Kirchhoff plate in the presence of flexural waves. Active sources are distributed exterior to the…
Dynamic interfacial trapping of flexural waves in structured plates
Stewart G. Haslinger, Richard V. Craster, Alexander B. Movchan +2
The paper presents new results on localisation and transmission of flexural waves in a structured plate containing a semi-infinite two-dimensional array of rigid pins. In particula…
Active cloaking of resonant coated inclusions for waves in membranes and Kirchhoff plates
J. O'Neill, O. Selsil, R. C. McPhedran +3
The dynamic response of a coated inclusion is considered in the context of active cloaking. The active cloak is achieved for a coated inclusion in the presence of membrane and flex…
Symmetry and resonant modes in platonic grating stacks
Stewart G Haslinger, Alexander B Movchan, Natasha V Movchan +1
We study the flexural wave modes existing in finite stacks of gratings containing rigid, zero-radius pins. We group the modes into even and odd classes, and derive dispersion equat…
Perturbation analysis of Mode III interfacial cracks advancing in a dilute heterogeneous material
Andrea Piccolroaz, Gennady Mishuris, Alexander Movchan +1
The paper addresses the problem of a Mode III interfacial crack advancing quasi-statically in a heterogeneous composite material, that is a two-phase material containing elastic in…
Interaction of an interfacial crack with linear micro-defects under out-of-plane shear loading
Gennady Mishuris, Alexander Movchan, Natasha Movchan +1
The interaction of an interfacial crack with small impurities is analysed on the basis of an asymptotic formula derived by the authors. The interaction between the main crack and t…
