Rugosidad y textura de superficies: Experimentos y simulaciones

In this work, some elements of fractal geometry are used to study and characterizesurface roughness. The materials under study are natural aggregates commonly used in the construction industry. Both experimental and theoretical approaches are used. In particular, we explore lacunarity analysis ?a multi-scaled method derived from fractal geometry-used for the describing patterns and dispersion. We illustrate its application to characterize surface roughness. Limitations and advantages of this approach are also discussed.
