Electromagnetic radiation during plastic flow and fracture of ice

Annotation

Discrete electromagnetic emission caused by a jump of plastic deformation and fracture of single-crystal and polycrystalline ice is revealed and investigated. An album of electromagnetic signals is compiled, which makes it possible, on the basis of the electromagnetic-signal shape, to identify and study the kinetics of mesoscopic events of structural relaxation that are related to the dynamics of dislocation pile-ups and cracks

Keywords

electromagnetic emission; dislocation; crack; self-organized critically; electromagnetic precursor of fracture; flicker-noise
