Odd dipole screening in radial inflation

Year: 2024

Type: article

Abstract: The inflation of an inner radial (or spherical) cavity in an amorphous solid confined in a disk (or a sphere) served as a fruitful case model for studying the effects of plastic deformations on the mechanical response. It was shown that when the field associated with Eshelby quadrupolar charges is nonuniform, the displacement field is riddled with dipole charges that screen elasticity, reminiscent of Debye monopoles screening in electrostatics. In this paper we look deeper into the screening phenomenon, taking into account the consequences of irreversibility that are associated with the breaking of Chiral symmetry. We consider the equations for the displacement field with the presence of "odd dipole screening," solve them analytically and compare with numerical simulations. Suggestions how to test the theory in experiments are provided.
