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 paper presents the results of modelling of temperature fields, stresses and deformations in formation of additive multilayer structure of aluminum alloy 1561, low-alloy structural steel of 09G2S grade and titanium alloy of Grade 2 grade. Based on the experimental results obtained earlier at the E.O. Paton Electric Welding Institute during application of additive deposits of these materials the computer modelling was carried out for improvement of technology of additive process. In course of calculations there was analyzed an effect of algorithm of sequence of additive layers deposition, namely deposition of cylinder shell on circle and on spiral, on distribution of temperatures in deposition and its resistance to external loads. It is determined that for formation of cylinder shells by additive method it is reasonable to use the spiral deposition technology and apply less heat-conducting structural materials, i.e. structural steels and titanium alloys. 10 Ref., 7 Figures.
Keywords: additive manufacturing, modelling, spiral deposition, cylinder shells, resistance, residual stresses
