Аннотация: The paper has considered the problem of determining the stress state of thin-walled waveguide structures during torsion. An analytical solution using the Bredt's formula has been considered and its comparison with a numerical solution using the finite element method has been performed. The numerical solution has been carried out usПоказать полностьюing a created volume model, and the load has been modeled as a set of concentrated forces distributed over the entire cross-section of the waveguide. It has allowed us to reduce the local effects in the form of complex stress state and increase the accuracy of the results. Comparison of the results has shown that the stresses calculated by the finite element method are always higher than those obtained by the Bredt's formula and it is necessary to take into account their maximum values. The deformation evaluation also has shown that the FEM calculations give larger twist angles than those obtained by the Bredt's formula for all the considered section sizes.
