INTEGRAL CHARACTERISTICS OF RIGID INCLUSIONS AND CAVITIES IN THE 2-DIMENSIONAL THEORY OF ELASTICITY

Representations of the components of the elastic-polarization matrices and the Wiener elastic capacity are obtained in terms of the coeffici ents of the Kolosov-Muskhelishvili complex potentials and the coeffici ents of the conformal representation, which define the geometry of an infinite elastic solid. A new integral characteristic of a rigid inclu sion-the Roben matrix, whose components are dimensionless, is proposed for use in applied problems. Examples of calculations, which correct formulae published previously elsewhere, are given. (C) 1998 Elsevier Science Ltd. All rights reserved.
