• Fractal analysis was applied to two-dimensional diffraction rings detedted with Imaging Plate (IP) in order to evaluate fatigue damage of materials. The material used in the study was low alloy steel (A508-2). About one eight image data in whole diffraction image data was analyzed to calculate fractal dimension. Four different parts of diffraction ring having different central angle were analyzed. It was found that fractal dimension shows a linear dependency on fatigue damage in case of sample to which plastic strain of 0.5% was applied.
