A Stable and Accurate X-FFT Solver For Linear Elastic Homogenization Problems in 3D by mspanish129 is a document available to read on EtoBox.
This document presents a novel X-FFT solver designed for three-dimensional linear elastic homogenization problems, addressing the limitations of traditional FFT-based methods in capturing material interfaces. By integrating the extended finite element method (X-FEM) with a modified preconditioning strategy, the solver achieves interface-conforming accuracy while maintaining numerical efficiency and stability. Computational studies confirm that the X-FFT solver effectively extends to 3D mechanics, demonstrat
