Nature of the rebinder effect in the fracture of inorganic dielectric and electrocohesion phenomena

The authors consider the effect of electric charges which appear on the sides of cracks developing in inorganic dielectrics under the action of a mechanical load on the change in strength of the dielectrics during their test in solutions and liquid media of various kind. Relation is stipulated.between the strengthof the dielectric and the intensity of the electrocohesion phenomena during fracture. It is concluded that the effectiveness of the use of a liquid medium to facilitate the fracture process is determined by the density of the electric charges on the sides of the growing crackand themagnitude of the relaxation time of the electric charges created by the liquid in the gap of the crack.
