FFT-based Homogenization

githubFFT

This code is an implementation of the standard FFT homogenization method developed by Moulinec and Suquet (1998) for microstructures with linear elastic isotropic phases. It computes the effective (/homogenized) stiffness of a microstructure with two phases (in the code the inclusion has the shape of a cylinder).

By now, many different FFT homogenization methods have been developded, see for example
