Abstract

This paper describes the use of flat, flexible lattices for demonstrating positive and negative Poisson's ratios for solids. Poisson's ratios describe the contraction or expansion of solids perpendicular to the direction in which they are stretched. These paper lattices can be used on an overhead projector for demonstration to an entire class, or they can be constructed and studied by students on an individual basis.
