Procedia Structural Integrity, 2017 Abstract: An experimental protocol was implemented to investigate possible correlations between the data provided by the Acoustic Emissions and the Pressure Stimulated Currents techniques and the role of the loading rate induced. Prismatic cement-mortar specimens were subjected to three-point bending (3PB) under various loading rates.

Journal of Geophysical Research: Solid Earth, 2022 Abstract The variations in the electric property of loaded rocks are essential in understanding the rock dynamics and fracturing process. Decades of laboratory experiments have revealed different behaviors of stress‐stimulated electric current due to the effects of rock types, loading modes, and detection methods.
