The research is aimed at developing effective methods of investigation and optimization of the stress-strain state on a contour partially reinforced thin elastic ribs curvilinear hole infinite plate for his force contact interaction with one or system rigid stamp on bounded smooth or ribbed surfaces. Using the condition of contact between the plate and ribbed stamp (stamps) of equality normal displacement contour points was constructed a systems of singular integral equations with kernels of Hilbert and logarithmic kernels for calculating the contact stresses under the stamp (stamp) and in the area gain. For the case of unification plate and stamps with zero-gap was found structure of these stresses at the ends of the contact zones and reinforcement. Was developed a method of mechanical quadrature and collocation, was investigated the impact on the stressed state of plates and enhanced physical and geometrical parameters of it amplifying ribs, shape of the hole, orthotropic material, the contact size, the number of stamp. Found coefficients intensity of effort at the ends of the contact zones and strengthening and parameters stiffness of the contour holes. Present a new approach to determining the stress-strain state and its optimization on partially reinforced contour curvilinear hole infinite plate under conditions of contact interaction with one or a system of smooth stamps at their landing in plate with a positive gap. Using the conditions of contact plate and stamps of equal curvatures in the contact zone, was constructed a system of singular integral equations with Hilbert kernel to calculate the contact stresses on the contour of the hole. The by method of mechanical quadrature and collocation on the influence the stress-strain state and strength form apertures and clearance, physical and geometrical parameters strengthening, orthotropic material, the contact size and number of stamps.
