Abstract
This article describes a technique for analyzing the spectra of localized deformation (LD) of products obtained by additive technology (SLM). We used digital-to-analog conversion (DAC) technology. To study the characteristics of periodic (from the place of fixation of the LD on
the estimated length of the sample) and piecewise linear (from the loading time) dependences, a technique for expanding the function of local deformations into a finite Fourier series is described.
