(Nanowerk Spotlight) Poisson's ratio describes the fundamental elasticity of any solid. Conventional materials contract laterally when stretched and Poisson's ratio expresses the ratio of transverse ...
When stretching an adhesive specimen along a longitudinal direction, it has a tendency to thin in a lateral direction. Measuring the relationship between how thin a material becomes during stretching ...
The Poisson ratio (defined as −1 times the ratio of lateral to applied elastic strains) describes the behaviour of stretched materials — positive Poisson ratios characterize the expected normal ...
