It is apparent in Figure B2 that the Poisson’s ratio approaches its theoretical value of 1
4 with increasing
plate thickness. Conversely, the Poisson’s ratio approaches 1
3 with decreasing plate thickness. The
internal length also affects the Poisson’s ratio substantially (Figure B2). The number of interactions for
points shown in Figure 9 can be determined by finding the volume of points whose distance to point of
interest is less than the cutoff radius. Hence, the number of interactions for a point located at x can be
computed as
