Sliding and Debonding Inclusions
Abstract
It was found by Mura and Furuhashi, J. App. Mech. 51 (1984) 308-310, when an ellipsoidal inclusion undergoes a uniform shear eigenstrain in the principal axis directions and the inclusion is free to slip along the interface, the stress field vanishes everywhere in the inclusion and the matrix. The main objective of the present grant DAAG29-85-K-0134 is to give more theoretical investigation on this amazing finding and to find applications to composite materials. This anomaly of sliding inclusions is based upon the fact that an ellipsoid is transformed into an identical ellipsoid by the uniform shear in the principle axis directions of the ellipsoid in the framework of linear theory as demonstrated by Mura. When the ellipsoidal inhomogeneity embedded in an infinite medium is subjected to an applied shear stress at infinity in the directions of the principle axes of the ellipsoid, the inhomogeneity behaves like a void if the interface can slide freely. Keywords: Sliding inclusions, Composite materials, Debonding, Inclusions, Shear stress, Linear theory.
