Elastodynamic Scattering From Inclusions Surrounded by Thin Interface Layers
TLDR
In this paper, the scattering of elastic waves by elastic inclusions surrounded by interface layers is studied by means of the null field approach and the properties of the interface layer enters through the boundary conditions on the inclusion.Abstract:
The scattering of elastic waves by elastic inclusions surrounded by interface layers is a problem of interest for nondestructive evaluation of interfaces in composites. In the present paper the scattering by a single elastic inclusion is studied. The scattering problem is solved by means of the null field approach and the properties of the interface layer enters through the boundary conditions on the inclusionread more

A general interface model for a three-dimensional curved thin anisotropic interphase between two anisotropic media
TL;DR: In this paper, an arbitrarily curved three-dimensional anisotropic thin interphase between two anisometric solids is considered and a Taylor expansion of the relevant fields in thin regions is used to model this interphase as a surface between its two neighboring media.

Dynamic effective properties of the particle-reinforced composites with the viscoelastic interphase
Peijun Wei,Zhuping Huang +1 more
TL;DR: In this article, the effects of viscoelastic behavior of the interphase on the dynamic effective properties of composite materials reinforced by the distributed coated spherical inclusions are studied and the effective wave numbers of composites are predicted from the coherent plane wave equation which is related to the forward scattering amplitudes of an individual inclusion.

A Comparison Between the Tiersten Model and O(H) Boundary Conditions for Elastic Surface Waves Guided by Thin Layers
TL;DR: In this article, a comparison between the boundary conditions (BCs) derived by Tiersten and the so-called O(h) BCs for elastic surface waves guided by thin films is made.
