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 ...
