摘要：

The elastic behavior of a spherical inclusion with a uniaxial dilatation is considered. As an example, the experimental data on stressed nanoclusters in doped semiconductors (As-Sb clusters in GaAs) are presented. The fields of displacements, elastic strains, and stresses are determined for spherical inclusions with uniaxial dilatation, and the specific features of these fields are revealed. The elastic energy of a uniaxial spheroid is calculated and compared with that for a triaxial spheroid. The relaxation mechanisms for the elastic field of the inclusion associated with the formation of prismatic dislocation loops are considered. (C) 2002 MAIK "Nauka/Interperiodica".
