Poisson ratio [pwä′sōn‚rā·shō] (mechanics) The ratio of the transverse contracting strain to the elongation strain when a rod is stretched by forces which are applied at its ends and which are parallel to the rod's axis.

The Young's modulus and Poisson's ratio were used to define material properties of polyester and steel cord. Anderson [4] later provided a justification of an expression of this form for the bulk modulus and noted that the elastic modulus would be approximately of the same form if the temperature dependence of Poisson's ratio could be ignored. Measuring the dispersion of these waves provides data on most of the film's physical properties, including thickness, hardness, elastic modulus, and Poisson's ratio. |
