Grain boundary stresses in elastic materials

Autor: S. El Shawish, T. Mede

Publikováno v: European Journal of Mechanics - A/Solids. 99:104940

A simple analytical model of intergranular normal stresses is proposed for a general elastic polycrystalline material with arbitrary shaped and randomly oriented grains under uniform loading. The model provides algebraic expressions for the local gra
