A Fourier transformation‐based method for gradient‐enhanced modeling of fatigue

Abstract: Summary A key limitation of the most constitutive models that reproduce a degradation of quasi‐brittle materials is that they generally do not address issues related to fatigue. One reason is the huge computational costs to resolve each load cycle on the structural level. The goal of this paper is the development of a temporal integration scheme, which significantly increases the computational efficiency of the finite element method in comparison to conventional temporal integrations. The essential constituent… Show more

“…They take advantage of the temporal scale separation for approximation of the response fields by a series. Thus the Fourier transformation-based integration (FTTI) was represented in [73,74] which searches for the displacement field as a Fourier series with angular frequency ω…”
