ON A MECHANISM FOR THE SHOCK POLARIZATION OF DIELECTRICS,

Abstract

A simplified account is given of a mechanism which it is hoped will explain the shock polarization of nonpiezoelectric dielectrics. The mechanism invokes a shock induced breakdown of the symmetry which is characteristic of non-piezoelectrics. The conclusion reached is that a polarization is developed which is proportional to the gradient of the stress. Consequently the entire voltage drop is predicted to lie across the shock front under open circuit conditions. In the AlkaliHalides a 10 volt signal is predicted for a stress of 100 kb. (Author)
