Active elastodynamic cloaking
Andrew N. Norris, Feruza A. Amirkulova, William J. Parnell
An active elastodynamic cloak destructively interferes with an incident time harmonic in-plane (coupled compressional/shear) elastic wave to produce zero total elastic field over a…
Predicting the pressure-volume curve of an elastic microsphere composite
Riccardo De Pascalis, I. David Abrahams, William J. Parnell
The effective macroscopic response of nonlinear elastomeric inhomogeneous materials is of great interest in many applications including nonlinear composite materials and soft biolo…
Source amplitudes for active exterior cloaking
Andrew N. Norris, Feruza A. Amirkulova, William J. Parnell
The active cloak comprises a discrete set of multipole sources that destructively interfere with an incident time harmonic scalar wave to produce zero total field over a finite spa…
Hyperelastic cloaking theory: Transformation elasticity with pre-stressed solids
A. N. Norris, W. J. Parnell
Transformation elasticity, by analogy with transformation acoustics and optics, converts material domains without altering wave properties, thereby enabling cloaking and related ef…
Employing pre-stress to generate finite cloaks for antiplane elastic waves
William J. Parnell, Andrew N. Norris, Tom Shearer
It is shown that nonlinear elastic pre-stress of neo-Hookean hyperelastic materials can be used as a mechanism to generate finite cloaks and thus render objects near-invisible to i…
Nonlinear pre-stress for cloaking from antiplane elastic waves
William J. Parnell
A theory is presented showing that cloaking of objects from antiplane elastic waves can be achieved by elastic pre-stress of a neo-Hookean nonlinear elastic material. This approach…
