The article deals with issues related to the calculation of electromagnetic fields (EM-fields) and the stress-strain state (SSS) of composite structures, taking into account contact deformation. A large number of technical and technological facilities work under the action of EM-fields. In some cases, the force action of the electromagnetic field is so significant that it can cause irreversible deformation or destruction of the elements. Electromagnetic forming (EMF) is one of the most striking examples of the force action of an EM-field. The efficiency of the technological operation of EMF is determined on the one hand by the efficiency of the inductor and on the other hand by the appearance in the workpiece of inelastic deformations. The calculation estimates of the inductor performance and inelastic deformation of the workpiece can be carried out on the basis of the distribution of the characteristics of the SSS. This work illustrates the implementation of such estimates for one class of technological systems consisting of a composite multi-turn inductor with an auxiliary screen, which is considered together with a workpiece that has a dent. The problem was solved by a numerical method, which is based on the finite element method. The peculiarities of contact interaction were taken into account by introducing layers of contact elements. The distribution of the components of the SSS is obtained taking into account the distribution of the EM-field in the quasi-stationary approximation for the time maximum. The rational values of some design and operational characteristics of the technological system are defined.

Keywords: inelastic deformation, electromagnetic field, the finite element method, contact interaction, electromagnetic forming.

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.
