Electromagnetic Force Distribution and Forming Performance in Electromagnetic Tube Expansion with Axial Compression

Transient Phenomena in Electromagnetic Forming Processes

The paper deals with finite element model for analysis of electromagnetic forming process of thin metallic sheets. The investigation starts with the FLUX simulation of transient electromagnetic field phenomena, continues with a transient structural analysis using ANSYS Structural under loads previously evaluated and ends with an ANSYS Multiphysics fully coupled analysis. The paper emphasizes th...

SHEET ELECTROMAGNETIC FORMING USING CONVEX PUNCH INSTEAD OF CONVAVE DIE

High speed and absence of a precise control over pressure distribution confine sheet Electromagnetic Forming into a die to simple shapes having shallow depth. It is possible to reach a higher depth by using a convex punch instead of a concave die. In this study, sheet Electromagnetic Forming on a punch and sheet Electromagnetic Forming into a die are investigated. The electromagnetic part of th...

Simulation Models of the Electromagnetic Forming Process

Suitable simulation approaches for the preliminary investigation of the electromagnetic metal forming process are presented. For this purpose an uncoupled (loose-coupled) simulation model is compared to a more rigorous sequential-coupled approach. As shown by examples, the connection between electromagnetic field and spatiotemporal evolution of the deformation of the workpiece cannot always be ...

Pulsed Beam Expansion of Electromagnetic Aperture Fields

The present contribution is concerned with an exact frame-based pulsed-beams expansion of planar aperture timedependent electromagnetic fields. The propagating field is described as a discrete superposition of tilted, shifted and delayed electromagnetic pulsed-beam waveobjects over the frame spectral lattice. Explicit asymptotic expressions for the electromagnetic pulsed-beam propagators are ob...
