Abstract

Buckling under uniform external pressure of а thin cylindrical shell joined at an edge with the circular plate is analyzed by means of the asymptotic method. Two types of buckling are considered. The axisymmetric buckling mode of the first type is localized on the surface of the plate. The buckling mode of the second type is closed to the buckling mode of the no stiffened shell and has many waves is the circumferential direction.
