poisson ratio from measured strains calculator online

Use poisson ratio from measured strains online for axial strain, lateral strain. Idealized linear material model where stated; no failure assessment, allowable stress, structural certification or compliance calculation is provided.

How to use it

Enter axial strain. Set lateral strain. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
axial strainMain input. Signed finite values. 0.001
lateral strainOption. Signed finite values. -0.0003

Calculation method

poisson_ratio = -lateral_strain/axial_strain (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply poisson ratio from measured strains to the case below, keeping the displayed units and assumptions. Idealized linear material model where stated; no failure assessment, allowable stress, structural certification or compliance calculation is provided.

Poisson Ratio from Measured Strains — worked case

Settings: lateral strain: -0.0003

Input:

0.001

Calculated result for these inputs:

Output:

{
  "poisson_ratio": 0.3
}

Choose the right tool

Choose the loading case and boundary conditions before entering values. Engineering stress differs from true stress; beam and thin-wall formulas require their stated idealizations. These calculators do not establish allowable loads or safe designs.

Limitations and common mistakes

  • Idealized linear material model where stated; no failure assessment, allowable stress, structural certification or compliance calculation is provided.
  • Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
