Scaling in Pressure Stimulated Currents related with rock fracture

Physica A: Statistical Mechanics and its Applications, 2008
Abstract The application of uniaxial stress in rocks is accompanied by the production of an electric signal which described by the term Pressure Stimulated Current (PSC). Here we present a statistical analysis of PSC time series from rock fracture experiments obtained from samples of calcite and cement mortar materials.

An analysis of pressure stimulated currents (PSC), in marble samples under mechanical stress

Physics and Chemistry of the Earth, 2006
Abstract The pressure stimulated current (PSC) technique was used in two variations, LSRT and SST for the investigation of the relations governing stress rate d S /d t , electric charge release and the behaviour of the damage parameter D , when a rock sample is driven to fracture by application of uniaxial compressional stress.

Experimental investigations of pressure stimulated currents from stressed sandstone used as precursors to rock fracture

International Journal of Rock Mechanics and Minings Sciences, 2021
Abstract Precursor information of rock fracture is a prerequisite for rock dynamic disaster (RDD) prediction. To investigate the precursor information of rock fracture based on pressure stimulated current (PSC), progressive loading (PL) and step-like loading (SLL) experiments on sandstone samples were conducted.

Investigation of acoustic emissions and pressure stimulated currents detected during bending of restored marble epistyles within the frame of log-periodic power-law models

Procedia Structural Integrity, 2018
The deformation of solid materials is a procedure which is accompanied by numerous effects like the emission of acoustic and electromagnetic signals or the generation of pressure stimulated currents. In the present work, we focus on the study of acoustic

Is pressure stimulated current relaxation in amphibolite a case of non-extensivity?

EPL (Europhysics Letters), 2012
The application of uniaxial stress on rocks is accompanied by the production of an electric signal which is described by the term pressure stimulated current (PSC). In this work the high rate step stress (HRSS) technique is applied, and the PSC relaxation in amphibolite samples from KTB drilling, is studied in the frame of non-extensive statistical ...
