Detailed Solution
Download Solution PDFExplanation:
Poisson's ratio is the ratio of transverse strain to longitudinal strain.
\(\mu = - \frac{{{\epsilon_{(lateral)}}}}{{{\epsilon_{(longitudinal)}}}}\)
For perfectly isotropic elastic material, Poisson’s ratio is 0.25 but for most of the materials.
The value of Poisson's ratio lies in the range of 0 to 0.5.
Poisson's ratio for various materials are:
- Cork: 0.0
- Aluminium: 0.31
- Cast iron: 0.21 – 0.26
- Steel: 0.27 – 0.30
- Stainless steel: 0.30 – 0.31
- Copper: 0.33
- Rubber: 0.5
