Elastic field perturbation by a misfitting ring inclusion

摘要

The plane elasticity problem of a circular ring inhomogeneity, with either a hollow or a rigid core, is confronted. A solution is obtained under a wide class of loading conditions, the main limitation being that internal stress sources (if any) are located in the matrix. In order to take into account interfacial residual stresses, misfit between matrix and inhomogeneity is allowed. Loading by misfit alone, by uniform remote stresses. and by an edge dislocation, are explicitly treated as special cases. (C) 2002 Elsevier Science Ltd. All rights reserved. [References: 5]
