ANALYSIS OF INFLAMMABLE STATE OF PURCHASE AT THE WALKING
Bubnovska Irina – Assistant Professor of the Department of “Electrical Engineering, Electrical Engineering
and Electromechanics” of the Vinnytsia National Agrarian University (3, Sunny St, Vinnytsia, 21008,

ANALYSIS OF INFLAMMABLE STATE OF PURCHASE
AT THE WALKING
On the basis of the equilibrium equation, the plasticity conditions in the zones of plane strain, the
equation of the connection of the components of the stress tensor and the strain rate tensor, an expression
was obtained for determining the stress state parameter, which makes it possible to estimate the deformity
of the workpiece material during rolling.
Key words: rolling, index stress state, strain rate, stress tensor, hydrostatic stress.

Technology, energy, agriculture transport AIC is a scholarly professional journal with a long-standing history and stable academic tradition, reflecting the evolution of engineering and technical sciences within the agro-industrial sector of Ukraine.
The journal was founded in 1997 under the title Bulletin of Vinnytsia State Agricultural Institute. According to the Resolution of the Presidium of the Higher Attestation Commission of Ukraine dated September 11, 1997, the publication obtained the status of a professional scientific journal, which enabled the publication of the main results of doctoral and candidate dissertations in technical sciences. From its inception, the journal positioned itself as an academic platform for addressing current issues of mechanization, electrification, and technical support of agricultural production. During 2001–2014, the journal was published under the title Proceedings of Vinnytsia National Agrarian University. Series: Technical Sciences (State Registration Certificate of Print Media KV No. 16644-5116 PR dated April 30, 2010). Throughout this period, a systematic approach to the selection and peer review of scientific manuscripts was established, the thematic scope of publications was expanded, and continuity of scientific directions as well as the development of sectoral engineering schools was ensured. Since 2015, the journal has been published under its current title, Technology, energy, agriculture transport AIC (State Registration Certificate No. 21906-11806 R dated March 12, 2016). The change of title reflected the expansion of the journal’s thematic coverage and its orientation toward interdisciplinary research in mechanical engineering, energy systems, electrical engineering, transport technologies, automation, and digital solutions for the agro-industrial complex.
