A material has a Poisson’s ratio of 0.5. If uniform pressure of 300GPa is applied to that material, What will be the volumetric strain of it?

A material has a Poisson’s ratio of 0.5. If uniform pressure of 300GPa is applied to that material, What will be the volumetric strain of it? Correct Answer Zero

As volumetric strain = (1-2μ)σ/E Here the value of μ is 0.5 so 1 – 2 * 0.5 becomes zero. Therefore whatever be the stress the value of volumetric strain will be zero.
