摘要：
Engineering calculation methods for stresses and strains in the concentration zones under elastoplastic deformation of structural elements are presented and analyzed. The Makhutov-modified Neuber equation is shown to be of the most reasonable accuracy for the assessment of kinetics of effective coefficients for stress and strain concentrations. The concept of scattered damage is introduced. The effect of scattered damages on the assessment of the stress-strain state of structural elements is demonstrated by the example of elastoplastic deformation of a hole-containing plate.
