Non-convex, ringing-free, FFT-accelerated solver using an incremental approximate energy functional
Ali Falsafi, Richard J. Leute, Martin Ladecký +1
Fourier-accelerated micromechanical homogenization has been developed and applied to a variety of problems, despite being prone to ringing artifacts. In addition, the majority of F…
Optimal FFT-accelerated Finite Element Solver for Homogenization
Martin Ladecký, Richard J. Leute, Ali Falsafi +4
We propose a matrix-free finite element (FE) homogenization scheme that is considerably more efficient than generic FE implementations. The efficiency of our scheme follows from a…
Elimination of ringing artifacts by finite-element projection in FFT-based homogenization
Richard J. Leute, Martin Ladecký, Ali Falsafi +5
Micromechanical homogenization is often carried out with Fourier-accelerated methods that are prone to ringing artifacts. We here generalize the compatibility projection introduced…
