| Abstract: |
The article explores the use of Acoustic Emissions (AE) and Non-Extensive Statistical Mechanics (NESM) to assess structural integrity in non-homogeneous systems. It introduces NESM, which is based on non-additive entropies, and discusses its application in analyzing acoustic activity in non-homogeneous systems. The study focuses on the acoustic activity in restored structural elements of the Temple of Parthenon, revealing similarities to previous studies on homogeneous materials. The article also discusses the use of NESM to analyze the acoustic activity in composite marble specimens under various loading conditions. The results provide insights into the behavior of the specimens and the effectiveness of restoration techniques. The study emphasizes the importance of considering material homogeneity and inhomogeneity in understanding the damage process. [Extracted from the article] |
