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…
Efficient topology optimization using compatibility projection in micromechanical homogenization
Indre Jödicke, Richard J. Leute, Till Junge +1
The adjoint method allows efficient calculation of the gradient with respect to the design variables of a topology optimization problem. This method is almost exclusively used in c…
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…
The universal emergence of self-affine roughness from deformation
Adam R. Hinkle, Wolfram Nöhring, Lars Pastewka
Most natural and man-made surfaces appear to be rough on many length scales. There is presently no unifying theory of the origin of roughness or the self-affine nature of surface t…
