Subcritical crack monitoring in rocks using combined electromagnetic and acoustic emission analysis

Year: 2025

Type: article

Abstract: This paper presents the use of a sensor fusion technique that combines acoustic emission (AE) and electric field (EME) sensors for the detection of cracking in rocks and man-made materials. The research focuses on subcritical cracking processes, which are often difficult to detect with traditional methods. While neither AE nor EME signals alone provide reliable detection due to noise and interference, their combination and use of signal processing enhances sensitivity and spatial resolution. This approach demonstrates the potential to develop reliable methods for use not only in laboratory settings but also under outdoor, natural conditions.
