An understanding of a material's microscopic architecture is important to improve its mechanical properties. Poisson's ratio, which celebrates its bicentenary this year, continues to provide a good ...

The Poisson’s ratio is a fundamental mechanical property that relates the resulting lateral strain to applied axial strain. Although this value can theoretically be negative, it is positive for nearly ...

If the Poisson’s ratio of the material if positive, then tensile/compressive strains in the x-direction produce compressive/tensile strains in the y- and z-directions, as shown below. Negative Poisson ...
