Micro-Focus X-ray Tomography (µX-CT), as non-destructive analytical technique, has been applied to obtain a virtual three dimensional image (tomogram) of material at a scale as low as 3 μm. VGStudioMAX and Image-J analytical software have been applied to extract quantitative information from the tomograms at 2D planes inside the samples where natural crack formation occurred due to stresses being applied to the sample.
The nature of crack formation has been investigated on different samples and has been tested against known criteria whether the morphology of the cracks follows a fractal geometry pattern.
This study focuses on coal,small and large bricks and smooth concrete and investigated the roughness of cracks within these structures to determine its fractal geometry correlation. It was found that the fracture surfaces of the mentioned samples follow fractal behavior in a wide range of length scale. The concept of fractal geometry and results obtained will be presented.
