Improved guaranteed computable bounds on homogenized properties of periodic media by the Fourier-Galerkin method with exact integration
Moulinec and Suquet introduced FFT-based homogenization in 1994, and 20years later, their approach is still effective for evaluating the homogenized properties arising from the periodic cell problem. This paper builds on the author's (2013) variational reformulation approximated by trigonometric polynomials establishing two numerical schemes: Galerkin approximation (Ga) and a version …
