Elastic Properties of Polycrystals: A Review

Abstract

The elastic properties of polycrystals depend on the single‐crystal elastic constants of the crystallites which build up the polycrystal and on the manner in which the crystallites are connected. Because of the technical importance of polycrystalline materials a lot of papers deal with the problem to calculate effective elastic constants of polycrystals from single‐crystal and structure properties. This paper gives a review concerning the most important theories and methods respecting this matter.
