Annotation

In assessing marginal change in the process of metal forming, plasticity is significantly affected by the rate of 
damage accumulation and their healing as derivatives of the stress state indicators. It is shown that under complex loading
conditions, when the damage accumulation rate (the first derivative of the stress state indicators) is more than 5 and the curvature
of the material deformation trajectories (the second derivative of the stress state indicators) is greater than 1, the scalar integral
criteria give the most reliable results destruction, taking into account the influence of the history of deformation on plasticity.
Keywords: marginal deformation, stress state indicator, curvature of deformation paths, plasticity resource, damage accumulation rate.

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.
