Shevtsova N. Contact interaction of plates with curvilinear contour and the detached elastic ribs by asymmetrical joint

Isotropic and orthotropic lamellar constructional elements with holes contour, which in part reinforced by asymmetrical ribs varying stiffness in the infinite plate; lamellar structure with circular contour. Engineering methodology calculation, research and optimization state of stress in the plates asymmetrical joint by disconnect elastic rib under force and couple interaction is developed. By method of complex variable theory and mechanics of deformable solids the systems of the integral-differential equations for definition power and couple contact stress are constructed and approximation method of their solution is developed. The influence on the stress state plates of asymmetry of reinforcement, anisotropy of a material, the form of the hole is investigated. The theory calculation of component lamellar structure which enables using method of calculation for design profiled spline joints and plates with extrusion is developed. The separate results are introduced into the industry. An orb of usage: machine construction industry and building.
