About

Poisson Ratio Calculator

Read full description

The Poisson's Ratio Calculator is a physics/math calculator designed to find Poisson's ratio, transverse strain, or longitudinal or axial strain quickly and easily. Features: - Instant calculation. - Results are copyable to other apps. - Formulas are included as reference. - Supports up to 16 decimal places. - Supports various units for each input. - Works seamlessly on both iPhone and iPad. - Lightweight, compact app optimized for everyday use. - Ad-free and built with privacy in mind. Poisson's ratio is the ratio of the relative contraction strain (transverse, lateral, or radial strain) normal to the applied load to the relative extension strain (or axial strain) in the direction of the applied load. Poisson's Ratio can be expressed as: μ = - ( εt / εl ) Where: μ : Poisson's ratio εt : Transverse strain (m/m, ft/ft) εl : Longitudinal or axial strain (m/m, ft/ft) Poisson’s ratio, named after Siméon Poisson, is the negative ratio of transverse to axial strain. When a material is compressed in one direction, it usually tends to expand in the other two directions perpendicular to the direction of compression. This phenomenon is called the Poisson effect. Poisson’s ratio (nu) is a measure of this effect. The Poisson ratio is the fraction (or percent) of expansion divided by the fraction (or percent) of compression, for small values of these changes.

Verdict

The call

The clearest difference is price: Beam Engineering lite at Free against Poisson Ratio Calculator's $2.99. Beam Engineering lite also leads on update cadence (every 5 months vs every 31 months). Poisson Ratio Calculator's advantage is in-app purchases (none vs 1) and ads (none vs shown). On device support there is nothing between them.
