AbstractThe work studied core elements of the hollow cross-section created by a promising technology that does not require large energy costs. The change in the critical forces depending on its transverse dimensions is revealed based on the numerical analysis of the hollow element stability under central compression. It is found that the material of the rod element influences the critical stresses. The paper shows that the calculations of the hollow element stability are coherent with the experimental data on models.
Keywordsnuclear power plant, metal, hollow element, calculation, stability, experiment.
