Abstract
The paper proposes the problem solution for interaction of two following factors: perforated plate reinforcement by a stringer system and its loosening by a number of circular holes and two cracks along the x-axis near each hole. The hole and crack edges are free from external loads. The riveted plate is subjected to tension by strengthening ribs via constant stresses. The action of riveted reinforcing strengthening ribs is modeled by unknown concentrated forces applied to anchor points.
An effective solution is proposed for the reinforcement by transverse strengthening ribs of plates weakened by stress concentrators (holes, cracks) under loading. The stress intensity and ultimate loads are found depending on geometrical and physical parameters of the problem.
