摘要/Abstract

摘要： Gurtin’s variational principle is used to derive the equivalence equalions for general linear elastodynamical problems of multiple inhomogeneities. An approximate expression on scattering field of two ellipsoidal inhomogeneities is obtained by the method of equivalent inclusions. And some numerical examples are presented.

关键词: set-valued extension, Steiner selection, a Jackson type estimate
