Abstract
The estimation of stress at a continuum point from the atomistic scale requires volume averaging over a region that contains this point. A hypothesis is put forth to obtain a lower bound for the size of this region based on an analogy to the Ising model. This hypothesis is tested on copper using two classical elasticity problems.
