In this paper, the main problems associated with the mechanical processing of parts of various types and purposes are investigated. On the basis of this, a new technology for processing and strengthening the surface layer of parts made of high-speed steel of the P6M5 brand using the combined RTS effect is proposed. A block diagram of the main addit...
An analytical method for calculating and forecasting static hydrogen fatigue of pipe steels intended for operation in corrosive-aggressive environments containing hydrogen sulfide has been developed. Mathematical calculations correlate well with experimental results (deviations do not exceed 5-7%), which is allowed in engineering predictive calcula...
The analysis of the moisture state of the zone of adjacency of the brick pilaster to the wall during its insulation from the inside is performed in this research. Brick pilaster is made of slotted ceramic bricks. The influence of filling the cavities of the slotted brick with cement-sand mortar on the moisture state of the adjacency zone was consid...
Recently, environmental problems have become more acute. In 1980, the International Union for the Conservation of Nature (IUCN) prepared the World Conservation Strategy. This document interpreted the term “sustainable development” as an inseparable link between social development and nature conservation. And already in 1992, after the United Nation...
На основі чинних нормативних документів складено алгоритм для виконання розрахунку попередньо напружених згинальних елементів за деформаціями. Скориставшись наведеним алгоритмом можна легко виконати необхідні розрахунки і зробити висновок про забезпечення (або незабезпечення) жорсткості елемента.
Стаття присвячена методиці розрахунку стиснутих залізобетонних елементів на основі деформаційної моделі за національними нормами з урахуванням впливів першого і другого порядку. Наведено алгоритм розрахунку стиснутих елементів за першою формою рівноваги.
The article is devoted to the calculation method of the compressed concrete elements based on...
