Application of wavelet-analysis of surface images for studying processes of plastic deformation and fracture at the mesoscale level

Abstract

A new method of numerical evaluation of surface degradation processes is suggested in the frames of the approach of physical materials mesomechanics. The numerical characteristics of wavelet-spectra and their graphic two-dimensional representation can be used for both estimation of optical images quality and improvement and for analysis of changes occurring in application of external loads to studied materials. The revealed proportionality between height (brightness) difference density and wavelet-spectrum energy allows one to use the energy, similarly to fractal dimensionality, for detection of plastic deformation stage processes.
