ПРЕДЕЛЬНОЕ СОСТОЯНИЕ СТЕРЖНЯ КРУГЛОГО СЕЧЕНИЯ ИЗ ИДЕАЛЬНО-ПЛАСТИЧНОГО МАТЕРИАЛА ПРИ РАСТЯЖЕНИИ С ИЗГИБОМ

Abstract

The result of the plastic analysis of the rod is presented in the form of the dependence of the limiting bending moment on the axial force. For a round rod made of an ideally plastic material, the boundary separating the zone of the elastic-plastic state of the cross-section material from the area of its plastic flow is determined. The results are necessary for the theoretical substantiation of the phenomenon of “stretching” of wires and cables – the residual inelastic elongation of long flexible threads.
