摘要

考虑了在材料不稳定的情况下，即在考虑材料非椭圆性的情况下，von Mises 桁架的屈曲过程。绘制了力-位移图。得出的结果使我们能够研究由平衡方程可能失去椭圆性的材料制成的薄壁结构（拱或壳）的屈曲。

Stability of the Von Mises Truss Under the Condition of Material Non-Ellipticity

The process of buckling of the von Mises truss in the case of material instability, i.e., with allowance for material non-ellipticity, is considered. Force-displacement diagrams are constructed. Results that allow one to study buckling of thin-walled structures (arches or shells) made of materials for which the loss of ellipticity of equilibrium equations is possible are obtained.
