Determination of microstructural parameters of random spatial surface fractals by measuring chord length distributions

An experimental procedure for determining the micro‐structural parameters of random spatial surface fractals is proposed. The procedure is based on chord length distribution measurements of planar sections of the investigated material at different linear resolutions, and comparison of the experimental results with the corresponding parameters of a well‐defined structure model. The variability of the model allows microstructures with arbitrary volume fraction and fractal dimension to be considered. Furthermore, both discrete and continuous scaling behaviour have been studied.
