Abstract
Wavelet analysis is applied to the characterization of the fretting damage of materials. Two cases are considered. In the first case, fretted surfaces in a Ti-6Al-4V alloy are quantitatively characterized by analyzing profilometric digital images of fretted surfaces. Through wavelet analysis, dominant length scales are determined as those regions in the scale-space where the energy of the wavelet transform and/or peaks of local concentration dominate. The second use of wavelets deals with the non-uniformity of the contact regions. In particular, wavelet analysis is employed to identify those regions.
