    Quantifying the Rock Damage Intensity Controlled by Mineral Compositions: Insights from Fractal Analyses by Özge Dinç Göğüş, Elif Avşar, Kayhan Develi, Ayten Çalık

    Published 2023-05-01
    “…We demonstrate crack intensity at critical stress levels where cracking initiates (σ<sub>ci</sub>), propagates (σ<sub>cd</sub>), and where failure occurs (σ<sub>peak</sub>) based on scanning electron microscope (SEM) images. Furthermore, the progression of rock damage was quantified for each rock type through the fractal analyses of crack patterns on these images. …”
