The procedure of gas-metal arc welding (GMAW) has received much attention in recent years and has numerous beneficial applications in the industry. The arc voltage, welding current and welding speed are three independent variables of this process that may affect the mechanical properties of the weld metal. As one of the most important mechanical properties of the weld metal, we can mention its yie...... hiện toàn bộ
Influence of Anticorrosion Pigments on Protective Properties of Epoxy CoatingsSoviet materials science : a transl. of Fiziko-khimicheskaya mekhanika materialov / Academy of Sciences of the Ukrainian SSR - - 2000

We investigated the impedance characteristics of epoxy coatings which contain chromate pigment or a mixture of phosphate and calcium-containing pigments in their primer layer. The coatings were applied on low-carbon and zinc-coated steels. The studies were performed in a corrosive medium which simulated the acidic atmospheric precipitation. We found that chromate pigment provides a greater passiva...... hiện toàn bộ
Influence of Cetyltrimethylammonium Chloride on the Strength of Silica Optical FibersSoviet materials science : a transl. of Fiziko-khimicheskaya mekhanika materialov / Academy of Sciences of the Ukrainian SSR - Tập 49 - Trang 170-179 - 2013

The evolution of strength of silica optical fibers aged in cetyltrimethylammonium chloride solution (CTAC) is investigated. The mechanical behavior of silica-coated and naked fibers is studied in contact with CTAC solutions of different concentrations. The results of our analyses prove that the immersion in CTAC drastically decreases the strength of fibers, especially near the critical micelle con...... hiện toàn bộ
Stress Concentration Near Curvilinear Holes and Notches with Nonsmooth ContoursSoviet materials science : a transl. of Fiziko-khimicheskaya mekhanika materialov / Academy of Sciences of the Ukrainian SSR - Tập 57 - Trang 331-343 - 2022

We present a survey of the results of investigations of the concentration of stresses in elastic bodies weakened by curvilinear holes and notches with nonsmooth contours. Special attention is given to the asymptotic approach to the investigation of stress distributions near stress concentrators in the case where the stress intensity factors at sharp vertices are found by using the stress concentra...... hiện toàn bộ
