Poisson’s ratio (ν) is the ratio of lateral strain to axial strain in a material when it is subjected to uniaxial stress.
Rubber has the highest Poisson’s ratio, close to
0.5, as it exhibits large lateral deformation when stretched.
Typical Poisson's ratios:
Rubber: ~0.5.
Steel: ~0.3.
Wood: ~0.1 to 0.2.
Concrete: ~0.2.
A metal rod is stretched, causing its length to increase from the original length L by ΔL. How is longitudinal strain determined when it is positive, indicating an increase in length?
