Methods of discretization of complicate shape spatial bodies and their systems has been elaborated. Stiffness matrix and nodes reaction vector for circular closed finite element and physical relations for interaction description in spatial bodies systems using special finite elements has been obtained. For case of dynamic loading theoretical basis for potential method consideration of out-of-plane waves diffraction on a barrier in anisotropic medium is developed. Corresponding fundamental solution has been determined and verified. Product Description popup.authors popup.nrat_date 2020-04-02 Close
