DEVICE FOR GENERATION OF MECHANICAL PULSE OF PRESSURE BY ELECTRIC EXPLOSION OF FOIL Russian patent published in 2014 - IPC G01N3/313 

FIELD: test equipment.

SUBSTANCE: invention relates to loading devices for creation of short-term intense pressure pulses and may be used for determination of mechanical properties of materials under extreme conditions of loading (high pressures and speeds of deformation). In the proposed device the reverse current conductors have configuration and location, which provide for compensation of impact of a compressing magnetic field, generated by current, flowing in ruptured sectors of foil, with a magnetic field, generated by current, flowing along reverse current conductors, at the same time the foil electrically ruptured conductor is made in the form of a loaded surface in the form of sectors for development of a mechanical pressure pulse distributed according to a cosine law.

EFFECT: creation of an electric rupture device, which removes limitations on the shape of a tested sample and expands area of its use with the possibility of profiling a pressure pulse along loading surface for reproduction of pulse loads distributed along amplitude.
