Abstract
In this paper, the lower-bound of direct methods is applied to fiber reinforced metal matrix periodic composites. Three boundary conditions for the localization problem are discussed and the influence of hardening matrix material is studied. Furthermore, in combination with homogenization theory, plastic material parameters are predicted by using yield loci fitting on the macroscopic limit stress domain. The proposed approach is validated through a numerical example of unidirectional periodic composites with square fiber patterns.
