ON INITIAL POSTBUCKLING EQUILIBRIUM AND MINIMUM ENERGY BARRIER OF AXIALLY COMPRESSED CYLINDRICAL SHELL

Abstract

The features of formation of the initial postbuckling equilibrium of axially compressed elastic circular cylindrical shell are studied in geometrically nonlinear formulation. The character of energy barrier change with the variation of axial load is computed.
