Solona Olena – Candidate of Technical Sciences, Associate Professor of the Department of General Technical Disciplines and Labor Protection, Vinnytsia National Agrarian University (3, Solnyschaya St., Vinnytsia, Ukraine, 21008, e-mail: solona_o_v@ukr.net).

Annotation

The article presents an analysis of the formalization of the statics of a granular discrete medium, as well as solid concretions in it. Based on the analysis, a formalization of the granular medium in the form of a viscous plastic model of the Bingham solid has been proposed. The equations obtained can be used to determine the distribution of stresses and densities of a granular medium with various mechanical properties and the pressure of a granular medium to the walls of a container of arbitrary geometric shape.The above equilibrium conditions and equilibrium violation for concretions that are found in a granular medium allow one to determine their possible displacements in a stationary medium too. The main purpose of obtaining the above equations is to use them when solving the problem of the movement of concretions in a container that is driven into an oscillatory motion.

Keywords: granular discrete medium, stress components, the density of the granular medium, the mobility of the granular medium, staticsof granular medium, solid concretion, bounding surface, contact conditions

History of journal:

In June 1994 the 2nd International Scientific and Technical Conference "Application of vibrations for technological purposes" was organized on the basis of Vinnytsia State Agricultural Institute. Leading experts in this field, noting the significant contribution to the school of Vibration Engineering under the leadership of P. S. Bernyk, proposed to create a professional all-Ukrainian scientific and technical journal "Vibration in engineering and technology..The journal was foundedat Vinnytsia State Agricultural Institute and P.S. Bernyk was elected to be the chief editor .
For all these years (since 1994) theJournal "vibration in engineering and technology" published  94 issues wherestudy of vibration effects, the creation of progressive energy saving technologies and equipment for their implementation were highlighted.
Currently Kaletnik H.M  PhD , professor, academician NAAS is the chief editor of the "Vibrations in engineering  and Technology"
The journal "Vibration in Engineering and technology", which has no analogues on the territory of Ukraine, is well known abroad.
