Abstract: The condition of the constituent elements of telecommunications and radio-electronic complexes is largely determined by the trends of changes in parameters of electro-radio components, properties of mechanical structures, and parameters of antenna and guidance systems. And one of the indicators that must be taken into account is thermoelectric elasticity. Information on models of thermo-electro elasticity of multi-layered structures, which form various basic elements of telecommunication and radio-electronic complexes, is necessary for determining the dynamics of changes in the technical condition of equipment under certain operating conditions. These cases can be described with the help of boundary problems of thermo-electro elasticity. A class of static boundary value problems is effectively solved for bodies bounded by coordinate surfaces of generalized cylindrical coordinates ρ,α, z ( ρ,α orthogonal curved coordinates on the plane, and z linear coordinates). The body is affected by a stationary temperature and electric field, surface disturbances (given voltages, displacements, or a combination of them) z = 0 and z = z1 homogeneous conditions of a special type are set on the remaining part of the surface. An elastic body is assumed to be transtropic (transversally isotropic), with an isotropy plane z = const . The transtropic layers of a multilayer body contact along the plane z = const . In the work with the method of separation of variables, exact solutions to several boundary problems about the thermo-electro elastic equilibrium of single and multilayer bodies are constructed.
