Abstract


This paper is devoted to the analysis of loading and deforming mechanics of a thin sheet metal by electro-hydraulic forming. A specific example using the finite-element LS-DYNA code demonstrates some features of a plasma expansion in discharge channel dynamics, pressure in the discharge chamber, loadings and deformation of a sheet metal part. The small influence of a shock wave on plastic strain of sheet metal part in comparison with influence of a hydrostream of a fluid is shown.
