title: Digital-to-analogue conversion of piecewise-linear and periodic functions of wave deformation in metals
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 onthe 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.
