OF THIN ELASTIC ENVELOPES UNDER THE EFFECT OF FORCE 
AND TEMPERATURE

UDC 539.3

The stressed-and-strained state of the most unfavorable 
representatives of envelopes of zero Gaussian curvature from the point 
of view of applicability of the St. Venant principle - the cylindrical 
ones - under forces and temperature fields with piecewise-smooth 
variation along the genetratrix and cosinusoidal variation along the 
contour is investigated. Results of an experimental investigation 
of the envelopes are presented.
