Study of the dependence of the maximum normal stresses in the sections of thin-walled rods on the curvature of the bent axis in the longitudinal bending

Objective. The aim of the study is to determine dependence normal stress on radius curvature a flexible rod at different thicknesses. Method. A method was applied maximum stresses in longitudinally compressed high flexibility using elliptic integrals. Result. Modeling thin-walled performed ANSIS calculation complex. Conclusion. exact theory for calculating rods allows you value axial force during longitudinal compression, which ends will close. When solving problems practical use this type rods, it interest stresses, and any stage deformation, makes possible choose dimensional parameters elastic element its material with greater accuracy.
