Abstract
In the given article the analysis of stress intensity factors (SIF) for semielliptical surface cracks in low-alloy steel using the finite element method was conducted. The results of the distribution of stress intensity factors along the front of the semielliptical surface cracks in the zones of structural stress concentrators are obtained.
