The Lennard-Jones(L-J) potential is assumed as a two-body potential. The tensile load is applied by elongating the fundamental cell longitudinally. The numerical results show that the stress decreases considerably as the size of the region for defining the stress decreases. It is found that more than 130 particles are necessary in the region for the stress concept to be applicable in continuum mechanics.
