Separation at the Interface of a Circular Inclusion and the Surrounding Medium Under an Incident Compressive Wave.

Abstract

Separation at the interface of a circular inclusion embedded in a matrix of lower characteristics impedance and subjected to incident compressive waves is investigated, both experimentally and analytically. In the experiment, the compressive waves were generated by small explosive charges. The qualitative analytical treatment is based on the methods of propagating stress discontinuities. It is shown that a compressive stress wave is converteed into a tensile wave after a refraction and a reflection inside the inclusion. The results of this paper apply to the behavior of fiber-reinforced composites under dynamic loading conditions. (Author, modified-PL).
