Abstract: Experimental laboratory work has been conducted to study electric signals of marble beams that have been subjected to three point bend tests. The specimens have suffered 12 abrupt loading steps up to failure and the corresponding BSC were recorded by means of copper electrodes placed in the lower surface of the sample. Alongside with the application of abrupt loading to the samples, BSC peaks were observed and then the current followed an exponentially decreasing relaxation process. In this paper the BSC peaks, the total charge, as well as the characteristic relaxation time variables are correlated with each other and also with the applied loading. The ultimate purpose is the evaluation of the fatigue of the sample using simple criteria.
