Thin-walled structure, by its nature, is subjected to loss of stability. In addition, the shell has a cutout, which reduces the critical load. The aim of this study is to determine critical stress of the shell under pure bending. The goal was achieved in two ways: experimentally and analytically. Experimental studies were carried out on a specially designed test bench with the use of a resistive strain gauge. In the analytical solution the form of buckled shell was assumed, and then Bubnov-Galerkin method was applied.
