Poisson's Ratio of a Material

Introduction to Poisson's Ratio Calculator

Poisson's ratio (ν) is a measure of the Poisson effect, which describes the expansion or contraction of a material in directions perpendicular to the direction of loading. It is defined as the negative ratio of the transverse strain (ε_t) to the axial strain (ε_a), where transverse strain is the strain in the direction perpendicular to the applied force, and axial strain is the strain in the direction of the applied force. A positive axial strain means that the material is stretched, while a negative transverse strain implies that it contracts in the perpendicular direction.

Parameter usage:

• transverseStrain = strain perpendicular to the applied force (must be negative)
• axialStrain = strain in the direction of the applied force (must be positive)

Output:

• Poisson's Ratio = the ratio indicating the degree of the Poisson effect in the material

Data validation

The transverse strain should be negative (indicating contraction) and the axial strain should be positive (indicating extension).

Summary

This calculator assists in determining Poisson's ratio, which is crucial for understanding the mechanical behavior of materials when they are subjected to stress.
