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. Webb15 nov. 2024 · Negative Poisson’s Ratio. As we said that the Poisson’s ratio values vary from 0 to .5. But for some Auxetics materials, the Poisson’s ratio is negative. What does that mean is that, for a change in …
