Non-Schmid Effects and Criteria for Dislocation Nucleation on Different Slip Systems at Grain Boundaries
Criteria for grain boundary dislocation nucleation are developed. A bicrystal containing two grain boundaries is placed under varying triaxial stress states using molecular dynamics. The local resolved shear, normal, and co-slip stresses needed for grain boundary dislocation nucleation are found. A...
