Experimental research on influence mechanism of loading rates on rock pressure stimulated currents
International Journal of Mining Science and Technology, 2023 The study of pressure stimulated current (PSC) changes of rocks is significant to monitor dynamic disasters in mines and rock masses. The existing studies focus on change laws and mechanism of currents generated under the loading of rocks.

Pressure Stimulated Currents (PSC)in marble samples
Annals of Geophysics, 2004 The electrical behaviour of marble samples from Penteli Mountain was studied while they were subjected to uniaxial stress. The application of consecutive impulsive variations of uniaxial stress to thirty connatural samples produced Pressure Stimulated ...

Correlation of pressure stimulated currents in rocks with the damage parameter
Annals of Geophysics, 2007 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 ...

Acoustic Emissions versus Pressure Stimulated Currents during bending of restored marble epistyles: Preliminary results [PDF]
Fracture and Structural Integrity, 2017 The efficiency of two modern sensing techniques, namely the “Acoustic Emissions” and the “Pressure Stimulated Currents” ones, when they are used as Continuous Structural Health Monitoring tools, is assessed experimentally.

Correlation between the electric and acoustic signals emitted during compression of brittle materials [PDF]
Fracture and Structural Integrity, 2017 An experimental protocol is described including a series of uni¬axial compression tests of three brittle materials (marble, mortar and glass). The Acoustic Emission (AE) technique and the Pressure Stimulated Currents (PSC) one are used since the ...

Acoustic emissions and electric signal recordings, when cement mortar beams are subjected to three-point bending under various loading protocols [PDF]
Fracture and Structural Integrity, 2017 Two experimental techniques are used study the response of cement mortar beams subjected to three-point bending under various load¬ing protocols. The techniques used are the detection of weak electric current emissions known as Pressure Stimulated ...
