description: The influence of cavitation effects during electrohydropulse stamping is considered. The effect of cavitation in the working fluid on the inner surface of the discharge chamber and its destruction is shown. A one-dimensional model of bubbly liquid has been developed that makes it possible to estimate the change in the pressure pulse parameters in the presence of a layer of bubbles of different porosity near the chamber wall. The problem was solved by the finite differnce method, with a numerical implementation in C++. The correctness of the model was verified by comparison with the test calculation of a similar problem for a homogeneous compressible fluid, modeled in the LS-DYNA 971 complex. It is shown that a layer of bubbly liquid makes it possible to almost double the pressure amplitude under the conditions of electrohydropulse stamping.
