A new mean field micromechanical approach to capture grain size effects

Although homogenization methods based on the Eshelby inclusion problem well capture the effects of heterogeneous local behaviours, volume fractions and morphologies of constituents on the macroscopic behaviour, inclusion size is still not considered. However, grain size effects are known to mainly participate on experimental results. In this contribution, we propose a new micromechanical approach based on the representation of the material as a …
