主 题:hemispherical inclusion elastic field Green's function eigenstrain half-space
摘 要:The elastic field induced by a hemispherical inclusion with uniform eigenstrains in a semi-infinite elastic medium is solved by using the Green s function method and series expansion *** exact solutions are presented for the displacement and stress fields which can be expressed by complete elliptic integrals of the first,second,and third kinds and hypergeometric *** present method can be used to determine the corresponding elastic fields when the shape of the inclusion is a spherical crown or a spherical ***,numerical results are given for the displacement and stress fields along the axis of symmetry (x3-axis).
