About Poisson's Ratio Calculator

The Poisson's Ratio Calculator is a useful tool for mechanical and civil engineering students. It calculates the ratio of lateral strain to longitudinal strain of a material under stress.

Formula: ν = - (ε_d / ε_L)

Key Points

• ε_L = Longitudinal Strain
• ε_d = Lateral Strain
• ν = Poisson’s Ratio (dimensionless)

Applications

• ✅ Elastic material property analysis
• ✅ Stress-strain calculations
• ✅ Structural and mechanical design

FAQs

1. What is Poisson’s Ratio?

Poisson’s Ratio (ν) is the negative ratio of lateral strain to longitudinal strain in a material subjected to stress.

2. What is the range of Poisson’s Ratio?

For most materials, Poisson’s Ratio lies between 0 and 0.5.

3. Why is Poisson’s Ratio important?

It is essential for determining material behavior under load, including deformation and stress distribution.

4. Which materials have high Poisson’s Ratio?

Rubber and elastomers typically have Poisson’s Ratio values close to 0.5.
