“…This software can simulate interacting of several fluids and deformable solids objects through using the Arbitrary Lagrangian Eulerian (ALE) algorithm which, in combination with Multi-Material technique and Fluid-Structure Interaction (FSI) technique, eliminates the problem of mesh distortion and allows solving the problem of moving liquids and gases inside of a closed complex shape volume [11]. In the context of EHF, a simulation of a discharge channel in liquid for the case of cylindrical symmetry was done in work [12], and for the case of a chamber with coaxial closely placed electrodesin works [13][14][15][16]. In these works, electric power laws were used to provide input in LS-DYNA for energy deposit laws into the discharge channel.…”

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.
