THEORETICAL PREDICTION OF PLASTIC STRAINS OF POLYCRYSTALS

Abstract

Plastic strain is considered a consequence of slipping on some of the 12 slip systems of facecentered-cubic single crystals. The polycrystal is assumed to be macroscopically homogeneous and initially isotropic -- that is, the crystal orientations, sizes, shapes and locations are random and uncorrelated. The rotations of the grains during deformation are neglected, and the average plastic strain in grains of a given orientation is calculated on the basis of the assumption that the grains under consideration are spherical and elastically isotropic.
