“…Since, as already noted, at δ=6.5 mm, loss of stability is excluded, the assessment of its bearing capacity is of decisive importance for the normal elastic operation of the shell, (Temirbekov et al, 2019) ó…”

“…in relation to the upper critical load , corresponding to the unacceptable phenomenon of flipping the shell to a new stationary equilibrium state with the formation of a local bend (Temirbekov et al, 2019) Each mechanical system with the loss of stability can behave differently. A transition to a certain new equilibrium state usually takes place, which in the overwhelming majority of cases, is accompanied by large displacements, the appearance of plastic (residual) deformations or complete destruction.…”

The article is devoted to solving the fundamental and applied problem of nonlinear structural mechanics of machines by introducing into the drum two additional stop cylinders with supporting rollers at the end and adjustable length, providing a given elliptical or circular shape of a flexible shell with a smoothly variable geometry in the area of its contact with compacted pavement material. Compaction of soil, gravel and asphalt concrete in the sphere of road is not only an integral part of the technological process of the roadbed, road foundation and surface construction, but it is actually the main operation to ensure their strength, stability and durability. The quality, cost and speed of road construction, the possibility of using fundamentally new technologies, structures and materials is largely determined by the availability of modern road machinery.

“…The ropes were preliminarily annealed at a temperature of 400-10000С, then they were cut into segments of a given length, which were split by grinding. Subsequently, steel-fiber-reinforcedconcrete structures for various purposes were made from the obtained fiber [1][2][3]. The disadvantage of this method was the loss of strength of wires during their heat treatment and the difficulty of washing and drying the finished fiber due to the lack of special equipment for these works.…”

The article presents the results of theoretical and, most importantly, experimental studies of some properties of steel-fiber-reinforcedconcrete reinforced with dispersed reinforcement from industrial wastes, namely, ITEX steel wire fiber from SPA INNOTECH from spent steel ropes, a large number of which are used as raw materials for fiber production, has accumulated in the region with the mining industry (East Kazakhstan region). The result of the research was indicators of tensile strength of fiber-reinforced concrete during bending of samples, characteristics of crack resistance, and impact strength indicators of fiber-reinforced concrete reinforced with fiber from industrial waste. Knowing and demonstrating these characteristics will make it possible to more effectively ensure the possibility of selling a new product on the building materials market. This publication has been carried out as part of the sub-project Technology for Manufacturing Fiber from Technogenic Wastes, funded by the Government of the Republic of Kazakhstan and the World Bank, Project for Stimulating Productive Innovations.

“…After the micro-arc oxidation observed increase in the intensity and broadening of diffraction lines (figure 6 b) with respect to the initial state ( figure 6 a), which indicates that the surface of the residual voltage, which is in service enhances the quality of the details. To determine the phase composition of the aluminum alloy sample treated with micro-arc oxidation implemented computerized statistical processing of results [18]. X-ray diffraction analysis of the pieces showed the presence of aluminum oxide phases.…”
