Abstract:
A sample of marble not possessing piezoelectric properties was subjected to uniaxial compressive loading and the response electric field potential was measured by a contactless method using a high-sensitivity electrometer. In the second experiment, weak electric potentials were applied via special electrodes to the opposite sides of the sample subjected to the same mechanical load. The electric potentials measured under the conditions of mechanical loading significantly change upon weak electrostatic polarization of the sample.Document Type: Research article
