TREShchINY SO SVYaZYaMI V PERFORIROVANNOY STRINGERNOY PLASTINE

An unlimited perforated plate, reinforced by a regular system of ribs is considered. Plate weakened by a periodic system of surface cracks. The model of a crack with end zones in which crack surfaces interact is used. The boundary value problem for the equilibrium of the periodic system of cracks is reduced to a singular integral equation. The condition of the limit equilibrium cracks is formulated taking account to the criterion of the limit traction of bonds.
