Modelling of fatigue damage in granitic rock by piezoelectric effect in quartz phase due to alternating current excitation
Saksala, Timo; Ruiz, Arturo Rubio; Kouhia, Reijo; Kane, Pascal-Alexandre Saidou; Hokka, Mikko (Peer reviewed; Journal article, 2023)This paper considers numerical modelling of hypothetical fatigue damage in granitic rock by alternating current (AC) excitation of piezoelectric properties of Quartz. For this end, a numerical method consisting of a rock ... -
Weakening of Compressive Strength of Granite by Piezoelectric Actuation of Quartz Using High-Frequency and High-Voltage Alternating Current: A 3D Numerical Study
Saksala, Timo; Rubio Ruiz, Rafael Arturo; Kane, Pascal-Alexandre Saidou; Hokka, Mikko (Peer reviewed; Journal article, 2023)Piezoelectric excitation of quartz mineral phase in granite using high-frequency and high-voltage alternating current (HF-HV-AC) is a potential new weakening pretreatment in comminution of rock. The present study addresses ... -
Weakening of tensile strength of granitic rock by HV-HF-AC actuation of piezoelectric properties of Quartz: a 3D numerical study
Saksala, Timo; Ruiz, Arturo Rubio; Kane, Pascal-Alexandre Saidou; Hokka, Mikko (Peer reviewed; Journal article, 2023)High-voltage and high-frequency alternating current (HV-HF-AC) excitation of piezoelectric properties of Quartz is a potential method to induce cracks in granite. This was recently shown in a numerical feasibility study ...
