Exploding wire phenomena and pressure wave generation in electrohydraulic forming.

Generation of copper nanoparticles by electro-exploding wire technique for various pressures of the surrounding medium

This paper presents the experimental results on explosion of copper wire at a discharge voltage of 9kV for the generation of Cu nanoparticles in nitrogen environment at different pressures. The current and voltage waveforms for different pressures of the nitrogen gas have been recorded by a current transformer and a high voltage probe. Nanoparticles generated by the electro exploded wire method...

Electrohydraulic shock wave generation as a means to increase intrinsic permeability of mortar

This article discusses the influence of compressive shock waves on the permeability of cementitious materials. Shock waves are generated in water by Pulsed Arc Electrohydraulic Discharges (PAED). The practical aim is to increase the intrinsic permeability of the specimens. The maximum pressure amplitude of the shock wave is 250 MPa. It generates damage in the specimens and the evolution of dama...

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...
