New structures of solving boundary problems (GSS) in the mechanics of solids and the theory of plates and shells, heat physics and electrodynamics for complex-shape locuses have been built, and their completeness has been substantiated. The Lagrange-Hermite interlocation formulas have been modified. The mathematical models of fields with helical and cyclic type of symmetry have been investigated. New constructional tools in the R-functions theory have been developed for solving the analytical geometry inverse problem in 3D space for blending in a pseudo model. The following has been investigated: laminar fluid flow in twisted pipes and coils; the initial-boundary creep problems for bodies of rotation; geometrically non-linear oscillations of orthotropic plates; oscillations of electromagnetic fields in waveguides containing geometric singularities; electrostatic fields in magnetrons and multi-pole deflectors; temperature fields in semi-axial resonators loaded with crystals
