Webb1 nov. 2024 · Rigid metals and polymers as a rule have a Poisson’s ratio ranging between 0.2 and 0.45 [2], [6]. For other soft metals and polymers, Poisson’s ratio is usually between 0.33 and 0.5. By contrast, only a few natural materials such as bone have negative Poisson’s ratio [7]. Webb11 feb. 2024 · In the limit of Poisson ratio of 0.5, the material behavior becomes incompressible. Real solids exhibit Poisson ratios <0.5. For a fluid under static conditions, it is possible to define a Poisson ratio in terms of the equation of state for the fluid. But it is definitely not equal to 0.5, particularly for gases.
