原始语种摘要: The article considers the issue of measures to increase the level of safe power loading of bearing elements of structures by determining the optimal complex of strength and plastic properties of the metal in consistent with the characteristics of the stress-strain state of a product containing a specific stress concentrator. Using the results of testing samples with circumferential notches for uniaxial tension, the threshold values of a special indicator of reserve properties of strength and ductility of steels—deformation endurance (break resistance) $B_{rb}$ are determined. Below these values, a reduction in the carrying capacity of the notched sample $\sigma_{NF}$ as a sign of stress concentration will be observed. A concept of the coefficient of carrying capacity $K_N$ of metal in a...
