Journal ArticleDOI
Structural fracture scales in shock-loaded epoxy composites
P. D. Stukhlyak,A. V. Buketov,S. V. Panin,S. V. Panin,Pavlo Maruschak,K. M. Moroz,M. A. Poltaranin,T. Vukherer,L. A. Kornienko,B. A. Lyukshin +9 more
TL;DR: In this article, the authors investigated fracture mechanisms of different scales on epoxy composite materials reinforced with silicon carbide microparticles of different concentrations and found that the high heterogeneity of the epoxy composites at different structural scales is one of the factors responsible for their physical and mechanical properties.
Journal ArticleDOI
Impact toughness of 12Cr1MoV steel. Part 2 – Influence of high intensity ion beam irradiation on energy and deformation parameters and mechanisms of fracture
S. V. Panin,S. V. Panin,Pavlo Maruschak,Ilya Vlasov,Ilya Vlasov,Victor P. Sergeev,Victor P. Sergeev,B. B. Ovechkin,V. V. Neifeld +8 more
TL;DR: In this paper, the impact toughness of 12Cr1MoV steel Charpy specimens has been studied in the range of temperatures from 20°C to 600°C, and it was found that ion beam treatment of steel deteriorates impact toughness at the tested temperatures by 5-42%.
Journal ArticleDOI
Steel Surface Defect Detection Using an Ensemble of Deep Residual Neural Networks
Journal ArticleDOI
Influence of Uneven Lighting on Quantitative Indicators of Surface Defects
Ihor Konovalenko,Pavlo Maruschak,Halyna Kozbur,Janette Brezinová,Jakub Brezina,Bohdan Nazarevich,Yaroslav Shkira +6 more
TL;DR: In this article , the impact of the illumination level on the quantitative indicators of mechanical damage of the rolled strip is investigated, and the obtained images of defects at light levels in the range of 2-800 lx were recognized by a neural network model based on the U-net architecture with a decoder based on ResNet152.
Journal ArticleDOI
Fatigue and failure of steel of offshore gas pipeline after the laying operation
Lyubomyr Poberezhnyi,Pavlo Maruschak,Olegas Prentkovskis,Iryna Danyliuk,Taras Pyrig,Janette Brezinová +5 more
TL;DR: In this paper, the residual lifetime of metal used for the offshore gas pipeline under a low amplitude cyclic load applying S- and J-methods for pipelaying is estimated.
