DEVICE FOR GENERATION OF MECHANICAL PULSE OF PRESSURE BY ELECTRIC EXPLOSION OF FOIL Russian patent published in 2009 - IPC G01N3/313 

FIELD: testing equipment.

SUBSTANCE: invention is related to loading devices for creation of short-term intense pressure pulses and may be used to detect mechanical properties of materials in extreme loading conditions (high pressures and speeds of deformation). Device consists of capacitance battery and loading unit, which represents direct and reverse current distributors. As reverse current distributor, current-conducting busbar is used, which consists of section arranged below level of exploded foil, and current in it flows in opposite direction to current of exploded foil, section, axis of symmetry of which passes through plane of exploded foil and direction of current in which coincides to direction of exploded foil current, and also sections, which join upper and lower sections of reverse current conductor. Distance to reverse current conductor, its height, depth of location of reverse current-conductor lower part and length of upper part of reverse current conductor are selected provided that magnetic field intensity value at foil border is equal to zero.

EFFECT: production of even distribution of generated mechanical pulse along surface of loaded sample in case of electrical explosion of foil.
