Конечные прогибы круговых цилиндрических оболочек перед потерей устойчивости под действием равномерного внешнего давления

To describe the axisymmetric deformation of circular cylindrical shell under uniform transversal pressure or in the condition of uniform compression the Marherr equation is used. The paper examines the bedding-in of the shell at the support contours at the condition of free axial displacement or without it. For the given boundary problems the analytical solutions in primitive functions is obtained and the main loading line of the shell is drown up.
