Query: Hyperelastic antiplane ground cloaking   Hyperelastic materials possess the appealing property that they may be
employed as elastic wave manipulation devices and cloaks by imposing
pre-deformation. They provide an alternative to microstructured metamaterials
and can be used in a reconfigurable manner. Previous studies indicate that
exact elastodynamic invariance to pre-deformation holds only for neo-Hookean
solids in the antiplane wave scenario and the semi-linear material in the
in-plane compressional/shear wave context. Furthermore, although ground cloaks
have been considered in the acoustic context they have not yet been discussed
for elastodynamics, either by employing microstructured cloaks or hyperelastic
cloaks. This work therefore aims at exploring the possibility of employing a
range of hyperelastic materials for use as antiplane ground cloaks (AGCs). The
use of the popular incompressible Arruda-Boyce and Mooney-Rivlin nonlinear
materials is explored. The scattering problem associated with the AGC is
simulated via finite element analysis where the cloaked region is formed by an
indentation of the surface. Results demonstrate that the neo-Hookean medium can
be used to generate a perfect hyperelastic AGC as should be expected.
Furthermore, although the AGC performance of the Mooney-Rivlin material is not
particularly satisfactory, it is shown that the Arruda-Boyce medium is an
excellent candidate material for this purpose.
