A second-moment incremental formulation for the mean …

1/3/2011· In this paper the incremental formulation for the MFH of elasto-plastic composites proposed in Doghri and Ouaar (2003) is enriched by including second moments of per-phase strain increment fields. The proposal is currently restricted to the classical elasto-plastic model with J 2 flow theory in each phase but is able to handle non-monotonic loading histories including cyclic ones.【Get Price】
