We present an atomistic study of the plastic deformation mechanisms occurring in columnar structures of nanocrystalline Ni, with particular emphasis on the process of dislocation emission form the grain boundaries. The samples are constructed with grain boundaries characterized by random tilt misori
Bulk strain, defined in terms of original and final dimensions of a specimen, correlates well with the logarithm of the average number of intercepts per unit length on test lines parallel to axes of symmetry after uniaxial deformation of an axisymmetric specimen. This suggests a definition of princi
