Using the finite element software complex LS-DYNA 971, the technique of simulating processes of Electro-Hydraulic forming is developed. The law of energy deposition is obtained from semi-analytical calculation. A simulation of complex EHF process, which includes discharge chamber with electrodes, plasma channel, water, deformable blank that is formed into a rigid die, is performed using the developed technique. The simulation is validated by experimental results. The developed technique significantly extends practical usage of numerical simulation of electrohydraulic forming and other electrohydraulic-based technologies.

A computer model of deforming a thin axisymmetric shell in Lagrangian-Euler coordinates under consecutive static and pulse loading was created. Consecutive loading reduces the wedging-out of a formed article and increases the stretching degree at the expense of magnification of deforming a flange folding in drawing. Deformation hardening of a material, elastic unloading, interaction of a shell with a dia, wave character of high-speed deforming and other factors are taken into account. An implicit finite-difference algorithm of a numerical solution, taking into account uniformity both features of statement and solution of two problems, was designed and a program was implemented. Calculations and experiments have shown a possibility of application ofthe computer model in practice of designing combined drawing.

In technological devices such as an electromagnetic hammer, a mobile part in form of a mechanical concentrator transforms impulse pressure of an electromagnetic field to an effort of stamping. The two-dimensional wave transformation of impulse pressure in an elastic concentrator with boundary conditions, conforming magnetic-pulse stamping by polyurethane, was reviewed. The implicit finite-difference algorithm of a numerical solution was designed and program was implemented. For the description of transformation of impulse pressure in the concentrator, a complex of dimensionless parameters was offered. On the basis of mathematical experiment, the transformation efficiency of pulse pressure by a mobile part was determined.
