The formula to calculate Poisson's Ratio is:
\[ \nu = -\left(\frac{\epsilon_L}{\epsilon_{\text{longitudinal}}}\right) \]
Where:
Poisson's Ratio is defined as the ratio of the lateral and axial strain. For many metals and alloys, values of Poisson’s ratio range between 0.1 and 0.5.
Let's assume the following values:
Using the formula:
\[ \nu = -\left(\frac{-0.06}{0.2}\right) \]
Evaluating:
\[ \nu = 0.3 \]
Poisson's Ratio is 0.3.
| Lateral Strain | Longitudinal Strain | Poisson's Ratio |
|---|---|---|
| -0.07 | 0.2 | 0.350000000000 |
| -0.06 | 0.2 | 0.300000000000 |
| -0.05 | 0.2 | 0.250000000000 |
