The Poisson Ratio Calculator is a valuable tool used to ascertain the relationship between a material's elasticity in the axial direction (Young's Modulus - E) and its resistance to shear deformation (Shear Modulus - G). The Poisson's ratio (ν) quantifies how a material deforms when subjected to stress in one direction, revealing its behavior in perpendicular directions.
Formula of Poisson Ratio Calculator
The formula to calculate the Poisson's ratio (ν) using Young's Modulus (E) and Shear Modulus (G) is:
ν = (3E - 2G) / (2(3E + G))
Here's a breakdown of the terms:
- ν: Poisson's ratio, indicating the material's deformation behavior.
- E: Young's Modulus, representing a material's elasticity along the applied force.
- G: Shear Modulus, portraying a material's resistance to shear stress.
This formula helps engineers and researchers predict how materials will respond to external forces and the resulting deformation in different directions.

Example of Poisson Ratio Calculator
Suppose a material has a Young's Modulus (E) of 50 GPa and a Shear Modulus (G) of 20 GPa. Plugging these values into the formula:
ν = (3 * 50 - 2 * 20) / (2 * (3 * 50 + 20))
This yields a Poisson's ratio (ν) of 0.3, elucidating the material's behavior when subjected to external forces.
