WebJun 1, 2024 · A FFT solver of a variational phase-field model for brittle fracture has been proposed in this paper. Relying on the staggered update scheme of [15], the phase-field and elastic problems have been separately solved both using the FFT method with fixed-point algorithm together with a convergence acceleration procedure. WebY = fft (X) computes the discrete Fourier transform (DFT) of X using a fast Fourier transform (FFT) algorithm. If X is a vector, then fft (X) returns the Fourier transform of the vector. If X is a matrix, then fft (X) treats the columns of X as vectors and returns the Fourier transform of each column.
