A Semi-Analytical Model for Buckling of Stiffened Cylindrical Shells

, 2013
Cylindrical shells are common configurations within the technology. The transition from the side to the bottom on a ship has the shape of a fourth of a cylindrical shell. Both ring and stringer stiffeners can be added to the shell for support.

Stiffened cylindrical shell parametric instability

"Purpose: The purpose of this thesis is to investigate the parametric instability of the stiffened cylindrical shell. The boundaries of the parametric instability regions are determined theoretically for a simply supported shell which is subjected to a periodic uniform axial load.
