Закономірності поширення низькочастотних електромагнітних та акустичних хвиль у середовищах із скінченою провідністю та заданими властивостями анізотропії Head Ulitko A.F., Registration Date 13-02-2002 Organization Taras Shevchenko Kiev university popup.description2 Kinematic and dynamic relations of geometrically nonlinear theory of elasticity with finite displacements are established. Thay include complete description of the finite deformations in cylindrical coordinates and their relations to those of lineаr elasticity; full description of the finite deformation tensor, and invariants, and its relation with Trefftz's stresses theory for the case of linear constitutive equations; nonlinaer equations of motion (equilibrium) and nonlinear boundary conditions. Statements of problems of seismoacoustics had been carried out for potential and vector wave fields in the cylindrical domains, and general solution for the vector fields was suggested through the vector eigen function method by A.F.Ulitko Product Description popup.authors popup.nrat_date 2020-04-02 Close
