Poisson Ratio

The Poisson ratio characterizes how much a solid expands in one direction as it is compressed in another. Therefore, a material with a negative Poisson ratio will compress in one direction as it is compressed in another. You can imagine squeezing the left- and right-most arms to contract the interior of the lattice shown above.
