Neighborhood effect on the strain distribution in linearly elastic polycrystals: Part 1 – Finite element study of the interaction between grains

Polycrystals are full of all kinds of heterogeneities which introduce stress concentrations. The local stress field in a grain does not depend solely on its crystallographic orientation. In fact, its neighborhood has also been shown to play a significant role. A definition and quantification method...
