TENSE LANDING OF THE RESERVED CIRCULAR BAR IN CIRCULAR OPENING INFINITELY IZOTROPIC PLATE

The exact solution of a task of the hard landing of a circular ring of constant cross-section in a circular hole of infinite izotropic plate, which is in conditions of the uniform stressed state at infinity is found. Simulating the ring by selfcontained curvilinear edge, calculation of which is based on a hypothesis of normal section, and the line of contact does not coincide with a center line, we obtained the integrodifferential equation with Gilbert's core for determination the contact efforts between a plate and a ring. The solution of a task is established by method of trigonometrical series. The minimum tension at which disconnection of the site of contact between a plate and a ring happens in two points is defined.
