Dislocation-Grain Boundary Interactions by the Quasicontinuum Method

Abstract:

Article Preview

The interactions between edge dislocations and the grain boundary have been studied by using quasicontinuum simulations. With an increase in the shear strain, dislocation pile-up is created and local stress concentration occurs at the head of the pile-up. The relationship between the stress concentration and the number of dislocations in the pile-up is discussed.
