Parabolic Metamaterials and Dirac Bridges
D. J. Colquitt, N. V. Movchan, A. B. Movchan
A new class of multi-scale structures, referred to as `parabolic metamaterials' is introduced and studied in this paper. For an elastic two-dimensional triangular lattice, we ident…
Blockage, trapping and waveguide modes for flexural waves in a semi-infinite double grating
Ian S. Jones, Natalia V. Movchan, Alexander B. Movchan
The paper presents a novel view on the scattering of a flexural wave in a Kirchhoff plate by a semi-infinite discrete system. Blocking and channelling of flexural waves are of spec…
Experimental and analytical insights on fracture trajectories in brittle materials with voids
D. Misseroni, A. B. Movchan, N. V. Movchan +1
Analytical models have been developed for fracture propagation over the last several decades and are now considered with renewed interest; the range of their applicability varies f…
Singular perturbations and cloaking illusions for elastic waves in membranes and Kirchhoff plates
I. S. Jones, M. Brun, N. V. Movchan +1
A perturbation approach is used for analysis of a near-cloak in shielding a finite scatterer from an incident flexural wave. The effect of the boundary conditions on the interior s…
