Diffraction Stress Analysis Using Direction Dependent Grain-Interaction Models
Résumé
Recently, so-called direction-dependent elastic grain-interaction models have been developed, which are capable of considering the effects of surface anisotropy or of a grain-shape (morphological) texture on the mechanical elastic constants and diffraction (X-ray) stress factors of polycrystals. The notion ‘direction-dependent grain-interaction’ signifies that different grain interaction constraints prevail along different directions in the polycrystal. This work summarizes recent developments and presents a comparison of direction-dependent elastic grain-interaction models.
