Abstract
The influence of various kinds of stress raisers on the processes of damage accumulation, initiation, and propagation of cracks in specimens of steel St3 under uniaxial tension has been considered. The investigated samples had a central aperture with diameter of ∅ = 5 mm or a transverse weld. The results of acoustic emission diagnostics showed that, despite the different nature of the stress raisers, the loading diagrams, the nature of damage accumulation and development of main cracks, the number of recorded acoustic emission (AE) events, and the activity of their recording, as well the dynamics of changes in the weight content of location pulses (\({{W}_{i}}\)) in the energy clusters of the low, medium, and high levels were quite similar, along with the values of these parameters during sample failure.
