COMPUTER SIMULATION ON NON-UNIFORM MULTIPLE SLIP IN FACE CENTERED CUBIC BICRYSTALS.

Abstract

Non-uniform multiple slip near a grain boundary plane in face centered cubic bicrystals was examined analytically. Mathematical models for movement and interaction of dislocations were introduced to have a quantitative constitutive relation describing plastic deformation of face centered cubic crystals. A new computer code for finite element structure analyses based on the relation was developed. By applying the code to deformation analyses of isoaxial bicrystals of the nominal strain incompatible type, the formation process and structure of shear strain in the multiple slip region were examined.
