Abstract: A method for electrohydraulically forming a blank of material includes—a blank of material to be deformed is placed between a mould and a blank holder, —a cavity containing electrodes is filled with liquid to a predetermined liquid level, —the blank of material is placed in contact with the liquid in the cavity, —a first electric discharge is generated between at least two electrodes so as to deform the blank of material against the mould, —the mould is brought nearer to the electrodes by moving the mould so as to reduce the distance between the electrodes and the blank of material to be deformed after the first electric discharge has been generated, —at least one other electric discharge is generated between at least two electrodes so as to deform the blank of material against the mould.

Abstract: An electrohydraulic forming device includes a mold, a tank having a first wall, and a first electrode and second electrode both placed in the tank and adapted to generate an electrical discharge to create at least one pressure wave. The first wall is rotationally symmetric about an axis of revolution, the electrodes have axes of revolution that are coincident with the axis of revolution of the first wall, and the first wall has a concavity oriented towards the mold.
