THE APPLICABILITY OF SAINT-VENANT'S PRINCIPLE TO MONOCOQUE STRUCTURES
B. V. Nerubailo, N. V. Zotova, R. Kh. Orlov, and S. V. Sukhorukova UDC 539.3 An extremely strong effect of boundary conditions on the character of damping of the stressed-strained state in a cylindrical envelope with a free edge under the action of concentrated normal forces transferred through an elastic frame has been revealed. Thus, under the effect of radial load at a large distance from the free edge of the envelope, the values of normal displacement and annular bending moment not only decrease on approaching the free edge but also increase, reaching a maximum value on the free edge of the envelope, which is in conflict with Saint-Venant's principle.
