In materials science and solid mechanics, Poisson's ratio (symbol: ν (nu)) is a measure of the Poisson effect, the deformation (expansion or contraction) of a material in directions perpendicular to the …

Jun 10, 2025 · Poisson’s ratio measures a material’s deformation when stretched or compressed. It quantifies how much it shrinks or expands in directions perpendicular to an applied normal force. For …

Poisson's ratio, a key material property describing the relationship between axial and lateral strain in solid materials. Typical Poisson's ratio values for metals, polymers, ceramics, and more, along with …

Poisson’s ratio is defined as the ratio between lateral strain (the amount that a material deforms perpendicular to the applied force) and axial strain (the amount that it deforms parallel to the force).

May 4, 2022 · In other words, it is the negative value of the ratio of transverse or lateral strain (x-direction) to axial or longitudinal strain (y-direction). The ratio takes its name from French physicist …

It is named after Siméon Poisson and is denoted by the Greek letter ‘nu’, It is the ratio of the amount of transversal expansion to the amount of axial compression for small values of these changes. What Is …

Nov 20, 2025 · Poisson’s ratio has dimensionless units. It was named after French mathematician Siméon-Denis Poisson, who first described it in 1811. For most common materials, the range of …

Nov 10, 2025 · When a force is applied to stretch or compress an object, the material changes shape not only in the direction of the force but also in the perpendicular directions. The Poisson Ratio is a …

Jul 23, 2025 · Poisson Ratio is defined as the negative ratio of the transversal strain to the longitudinal strain. It basically compares the change in the breadth of an object with respect to the change in the …

Poisson’s ratio indicates how much a material will compress or expand in one direction when stretched in another. For most materials, Poisson’s ratio falls between 0 and 0.5.
