FFT‐based simulation of evolving microstructures utilizing an adapting reduced set of Fourier modes

چکیده

Abstract The mechanical behavior of a periodic heterogeneous microstructure may be predicted by using fast Fourier transform (FFT) based simulation approach. To reduce the computational effort this method, we introduced model order reduction (MOR) technique utilizing reduced set modes for computations in space. increase accuracy MOR developed geometrically adapted sampling pattern choosing considered on representation phases within microstructure. Since phase distribution of, example, martensite and austenite polycrystalline evolves with increasing or thermal loads, should also evolve according to underlying micromechanical fields. We present adaptability adaptive investigating fields polycrystal considering such transformations.

Extension Ability of Reduced Order Model of Unsteady Incompressible Flows Using a Combination of POD and Fourier Modes

In this article, an improved reduced order modelling approach, based on the proper orthogonal decomposition (POD) method, is presented. After projecting the governing equations of flow dynamics along the POD modes, a dynamical system was obtained. Normally, the classical reduced order models do not predict accurate time variations of flow variables due to some reasons. The response of the dynam...

Simulation of an Airy Beam with Optical Vortex under Fractional Fourier Transforms

First, this study obtained the fields of an Airy beam (AiB) with optical vortex (OV) for a Fourier transform (FT) system and a fractional Fourier transform (fractional FT) system; thereafter, their intensity and phase patterns were simulated numerically. The splitting on each line of the phase pattern indicates the position of an OV. The results show that the OV position will change when the po...
