Abstract

Observations of the fracture-induced electromagnetic effect in metals have recently been reported by the author. This paper presents a physical model for explaining this new effect. The reasoning attributes the observed electromagnetic effect to dislocationelectron interactions in a metal. The frequency of the emitted radiation has been calculated from Bohr's correspondence principle and potential on the basis of Hertzian dipole radiation. The proposed physical model predicts emission of electromagnetic waves at distinct transition stages of elastic-plastic deformations. The paper also presents some of the experimental results, being obtained by the author, which confirm the practicability of this approach.
