“…In particular, the relationship of the estimated physical parameters with the size of the plastic zone and the concentration of micro cracks in it was considered [2]. The mechanical properties of structural steels are studied by acoustic and magnetic methods in the process of stretching flat specimens with a concentrator and the physical parameters characterizing the achievement of the ultimate state corresponding to the yield strength and strength of structural materials are determined [3].…”

In this paper, a systematic study of the microstructure damage process of metals and alloys was carried out. The main elements of the microstructure surface image, as well as the rules for the formation and interaction of rough slip traces and cracks to determine the model of damage accumulation on the image of the microstructure surface under cyclic loading are determined. A classifier that allows to determine the number of loading cycles before a sample goes out of service is proposed. A modernized structure of the convolutional neural network was developed to classify images of the damaged microstructure of the metals and alloys surface. The proposed classifier for determining the number of loading cycles made it possible to achieve a classification accuracy of 78.43%.

Failure risk assessment of pressure vessels and piping systems is an important part of their integrity management. Obviously, there are many shortcomings in risk analysis using only traditional procedures, which are mostly qualitative or conservative by nature. This study develops a novel limit analysis method using quantitative magnetic measurements to determine the failure risk of steel vessels. Firstly, the correlation between the physico-mechanical properties of a pressurized steel cylinder and the magnetic coercive force was obtained by hydraulic tests, it is found that increasing internal pressure leads to an increase in the coercive force, and the magnetomechanical behaviour can be described by a linear general expression. By solving the inverse problem, it is possible to diagnose the transition of the structure to the yield region or the fracture region based on the measurements of coercivity, which enables us to conduct the risk assessment prior to the failure of a pressurized cylinder, validated by a full-scale hydrostatic burst test. Finally, a quantitative criteria for identifying the structural failure of the pressurized cylinder was established based on coercivity measurements.
