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.
