Poisson Effects in Beam Bending

Poisson effects in beam bending describe how a material changes shape in directions perpendicular to the applied force. When a material is under uniaxial stress, it stretches or contracts along the load and also changes in the crosswise directions. Poisson's ratio, written as v, measures the ratio of transverse strain to axi...

When a material is subjected to uniaxial stress, the material undergoes elongation or contraction in the direction of the applied stress.

At the same time, deformation occurs in the transverse direction to the applied stress, governed by Poisson's ratio.

The deformation in the transverse direction will result either in expansion or...
