Question

Poisson's ratio can not have the value:

• A. 0.1
• B. 0.7
• C. 0.2
• D. 0.5

Answer 1

The correct option is B 0.7

The Poisson's ratio of a stable, isotropic, linear elastic material will be greater than −1.0 or less than 0.5 because of the requirement for Young's modulus, the shear modulus and bulk modulus to have positive values. Most materials have Poisson's ratio values ranging between 0.0 and 0.5.

Hence 'B' is the correct option.
