Correlation of pressure stimulated currents in rocks with the damage parameter
Main Article Content
Abstract
Pressure Stimulated Current (PSC) experiments were conducted on marble samples to correlate PSC with the
damage parameter, D. The phenomena and procedures taking place in the vicinity of the fracture limit were observed
and analytically described. PSC recordings were conducted by application of uniaxial compressional
stress, both at a constant stress rate and at a constant deformation rate. A linear relationship was shown to exist
between the emitted PSC and the damage parameter which quantifies the deviation from linear elasticity and the
concentration of microcracks.
