Позорная война рф против Украины

Начата 20 февраля 2014 и полномасштабно продолжена 24 февраля 2022 года. С первых же минут рф ведет ее с нарушением законов и правил войны, захватывает атомные станции, уничтожает бомбардировками мирное население и объекты критической инфраструктуры. Правители и армия рф - военные преступники. Все, кто платит им налоги или оказывают какую-либо поддержку - пособники терроризма. Народ Украины вас никогда не простит и ничего не забудет.

The work presents the results of modeling the temperature fields, stresses and deformations during formation of the additive multi-layer structure of aluminium alloy 1561, low-alloy structural steel of 09G2s grade and titanium alloy Grade 2. On the basis of experimental results, obtained at the E.O. Paton Electric Institute, the computer modeling was carried out during the additive surfacing of these materials to improve the technique of the process conducting. In the course of calculations the effect of algorithm of successive deposition of additive layers (surfacing of cylindrical shell around the circumference or in spiral) on distribution of temperatures during surfacing and its resistance to external loads was analyzed. It was established that during the formation of cylindrical shells by an additive method it is rational to apply the technology of surfacing in spiral and to use the less heat-conducting structural materials (structural steels, titanium alloys). Ref. 21, Table 1, Fig. 10.
