Characteristics of Development of Fatigue Cracks in Steel under Low-Level Operation Loading

Autor: A. N. Polyakov, G. V. Moskvitin, M. S. Pugachev, S. G. Lebedinskii

Publikováno v: Journal of Machinery Manufacture and Reliability. 49:144-149

An assessment method for characteristics of low-rate development of fatigue cracks under operational loading is proposed. The method is based on the decrease in the irregular loading level by conservation of its conformity during crack growth. The co

Temperature Distribution in the 'Material-Coating' Interface from a Fast-Moving Heat Emission Source for Electromagnetic Surfacing

Autor: A. V. Lyudagovskii, V. A. Polukhin, V. G. Dmitriev, G. V. Moskvitin, A. A. Loktev, Kh. A. Dianov

Publikováno v: Journal of Machinery Manufacture and Reliability. 48:259-267

During simulation of the surfacing process, it is proposed to present the heat emission source in the form of the system of instantaneous point sources flickering for some time; and the period between flashes tends to zero. The final results of the t

Influence processes freezing and thawing of permafrost soils on underground pipeline’s stress-strain state

Autor: G V Moskvitin, Yulia Grigorieva, Oleg Naumov

Publikováno v: Procedia Structural Integrity. 20:53-56

The positions of the underground routing pipeline under conditions of the effect of the freeze-thaw processes in the permafrost soils are simulated in the paper. The change in seasonal temperatures leads to the emergence of thermokarsts, heaving and

Determination of Damage Tolerance of Steel Cast Items of Railway Structures

Autor: S. G. Lebedinskii, M. S. Pugachev, G. V. Moskvitin, A. N. Polyakov

Publikováno v: Journal of Machinery Manufacture and Reliability. 47:532-536

The regularities of propagation of fatigue cracks have been studied in samples cut from a freight car bolster. Peculiar attention is paid to simulation of loading on the electrohydraulic test facility on the basis of operation load repeatability. The
