On mesoscale analysis for composite materials using s-FEM (some trials on three dimensional elastic plastic analysis)

Three-scale finite element analysis of heterogeneous media by asymptotic homogenization and mesh superposition methods

“…This implies that the 3D large-scale analysis is very difficult. Therefore, some researchers are attempting to use the preconditioned iterative solver (Shinmura et al, 2002;Okada et al, 2003). Shinmura et al (2002) found that the convergence is not obtained for some cases.…”
