Question

For homogeneous isotropic material, which one of the following cannot be the value of Poisson's ratio?

Options

• 0, 1

• - 1

• 0, 5

• 0, 8

Answer 1

0, 8

Explanation:

Because of the criterion, Poisson's ratio for homogeneous isotropic material must be between - 1.0 and + 0.5. Shear modulus and bulk modulus must be positive for Young's modulus to be positive.

As a result, the Poisson's ratio for homogeneous isotropic material cannot be 0.8.
