Syaskyy V. Contact interaction of curvilinear contours of plates and two-coherent stamps with angular points

Isotropic and orthotropic plates with curvilinear holes, contours of which interact with one- and two-coherent stamps that have angular points; circular discs, which interact with the friction with the system of two rigid stamps. Development of methodology for identification, research and optimization of stress state on the contour of the hole of the plate. The systems of singular integral equations with logarithmic kernels to determine the contact stress are built using methods of complex variable theory and mechanics of contact interaction. The approximate methods to solve systems of integral equations with logarithmic kernels are developed. The influence on the tense state of plates of form of opening, orthotropy of material, coherence of stamps and their geometrical parameters and frictional forces are investigated. The proposed theoretical framework make it possible to use the calculation method for the design of brake systems, friction gear, devices for fastening instruments in wells. Individual results of the study are introduced into production. Scope of application: engineering, construction, transportation.
