PS02 A Disclination Model Applied to Elastic Incompatibility Stress in Symmetric and Asymmetric Tricrystals

Abstract

A disclination is a line defect which violates rotational symmetry of elastic body. We propose a disclination-dislocation model for the elastic deformation of tricrystals in order to calculate the elastic incompatibility stress which arises around the grain boundaries junction in tricrystals when the crystal is deformed by external load. The calculated stress is compared with the result of FEM analysis of elastically anisotropic tricrystals.
