摘要：The article presents the method of calculating beams with a corrugated wall on the stability of a flat bending shape. The problem reduces to a differential equation of fourth order with respect to the twist angle. The solution is performed numerically by the finite difference method. A comparison of the results with the software package LIRA is presented.
