Method for determining cracking parameters, and device for applying the method

The method according to the invention, characterised in that a transducer (2) is disposed at the point where a crack (3) in a pattern (1) is propagating, whereupon from the side of only one of the edges of the crack (3) propagating simultaneously in the transducer (2) an electric field is generated from one of the sides of the base (3a) of the crack (3) and from the side of the point (3, 6) to the transducer (2) by supplying an electric current, while the measurement of the electric parameters of the transducer (2) is carried out at the current supply points. … The device according to the invention, characterised in that the feeder electrodes (5, 6) for the current supply to the transducer (2) are situated at the base (3a) side and the point (3b) side of the crack (3), while the measuring elelctrodes (7, 8, 9) are arranged in the immediate vicinity of the feeder electrodes (5, 6). ……
