Non-plane wave scattering from a single eccentric circular inclusion – Part I: SH waves

Wolfgang Weber, Bernd W. Zastrau
In this contribution, an analytical formalism for investigating the scattering behaviour of a single multi-layered inclusion in a homogeneous isotropic matrix under the influence of non-plane elastic SH waves is derived. Herein, the inclusion is assumed to have a circular shape with its layers being eccentrically arranged. Numerical examples are performed with Textile Reinforced Concrete, a new building material in civil engineering. Within these investigations both shielding and amplification of SH waves is shown.
