摘要：
The dynamic problems for two-phase piezomagnetoelectric nanosized bodies with account for surface and interphase effects and damping are considered. For these problems we propose the new mathematical model generalizing the models of the elastic medium with damping within the Rayleigh approach accounting for surface and interphase effects in the cases of piezoelectric and magnetoelectric materials. The finite element approximations are proposed for solution of these problems.
