Efficient topology optimization using compatibility projection in micromechanical homogenization

  title={Efficient topology optimization using compatibility projection in micromechanical homogenization},
  author={Indre J{\"o}dicke and Richard J. Leute and Till Junge and Lars Pastewka},
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 combination with traditional Finite-Element-Analysis, whereas Fourier-based solvers have recently shown large efficiency gains for homogenization problems. In this paper, we derive the discrete adjoint method for Fourier-based solvers that employ compatibility projection. We demonstrate the method on the optimization…

A finite element perspective on non-linear FFT-based micromechanical simulations
Fourier solvers have become efficient tools to establish structure–property relations in heterogeneous materials. Introduced as an alternative to the finite element (FE) method, they are based on

This Note is devoted to a new iterative algorithm to compute the local and overall response of a composite from images of its (complex) microstructure. The elastic problem for a heterogeneous
Elimination of ringing artifacts by finite-element projection in FFT-based homogenization
It is demonstrated that the compatibility projection for linear finite elements while maintaining Fourieracceleration and the fast convergence properties of the original method yields an efficient computational homogenization scheme that is equivalent to canonical finite-element formulations on fully structured grids.
A numerical method for computing the overall response of nonlinear composites with complex microstructure
An alternate method based on Fourier series which avoids meshing and which makes direct use of microstructure images is proposed, based on the exact expression of the Green function of a linear elastic and homogeneous comparison material.
Finite strain FFT-based non-linear solvers made simple
Computational micromechanics and homogenization require the solution of the mechanical equilibrium of a periodic cell that comprises a (generally complex) microstructure. Techniques that apply the
