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.
Keywords: 316L powder steel, SLM technology, sample, stretching, elongation, wave spectrum, digital-analog conversion, Fourier interpolation.
Funding agency
The research presented in this article was carried out with the financial support of a grant from the administration of the Tula region in 2022: ``Investigation of the mechanism of the wave nature of deformation and its connection with the orthotropy of the physical and mechanical properties of selective laser fusion products'' (contract DS/126).
