Authors: Свирид, Михаил Николаевич; Трофимов, И.
Abstract: Описан механизм трения ферромагнитной пары материалов ШХ-15 по стали 3 в условиях возвратно-поступательных движений, с добавкой порошка донора Ni в моторное масло М10Г2к. Отмечены структурные изменнения, которые перетерпевает ферромагнитный материал в магнитном поле и при трении.2017-01-01T00:00:00ZSingle-crystals as an indicator of fatigue damageKaruskevich, M.V.Zasimchuk, E.E.Radchenco, A.I.https://er.nau.edu.ua/handle/NAU/322842017-12-26T12:53:16Z1992-01-01T00:00:00ZTitle: Single-crystals as an indicator of fatigue damage
Authors: Karuskevich, M.V.; Zasimchuk, E.E.; Radchenco, A.I.
Abstract: The possibility of using specially prepared single crystals as indicators of fatigue damage is outlined. Results are described of an analysis of deformation patterns developed in the single-crystal indicator surface, under fatigue and static loading. It is shown that the density and direction of deformation bands correlate with the number of loading cycles.

Authors: Karuskevich, M.V.
Abstract: The investigations of the new fatigue sensor that was carried out at the wide range of cyclic loads conditions show the ability of the indicator application in Structural Health Monitoring systems of planes, bridges, vessels, and other structures. Accumulated fatigue damage may by estimated by the intensity of deformation relief, i.e. by its extrusion/intrusion and persistent slip bands structures on the indicator surface.

Abstract: Two approaches to aircraft fatigue monitoring by the computer-aided analysis of surface structures are described: (a) application of fatigue indicators attached to the aircraft unit; (b) the direct observation of the alclad aluminium alloys surface. The evolution of aluminium surface state has been monitored at various fatigue loading regimes. Some parameters have been used for the quantitative analysis of surface structures: (a) density of slip lines for single-crystals; (b) intensity and fractal dimensions of the deformation relief for polycrystalline aluminium. The possibility of a fatigue process prediction both at crack initiation stage and fatigue crack propagation stage is shown.
