Контактне деформування складеного індуктора із допоміжним екраном при дії електромагнітного поля

The paper discusses issues concerning the deformation of a system of conductive bodies under the action of the electromagnetic field. Problem of nonlinear deformation of the compound coil with an assistant for electromagnetic forming of sheet workpieces is considered as a practical application. The problem is solved by the finite element method. Contact interaction is modeled by the introduction of special layers of contact finite elements. Spatial-temporal distributions of the main components of the electromagnetic field are obtained. The ability to review the problem of deformation in the quasi-stationary formulation is justified. The distribution of the main component of the stress-strain state is presented. The influence of the current magnitude at the maximum stresses is evaluated.
