what is poissons ratio
Answers
Answer:
Poisson's ratio :-
The ratio of the proportional decrease in a lateral measurement to the proportional increase in length in a sample of material that is elastically stretched.
Explanation:
In materials science and solid mechanics, Poisson's ratio is a measure of the Poisson effect, the deformation of a material in directions perpendicular to the direction of loading. The value of Poisson's ratio is the negative of the ratio of transverse strain to axial strain.
Answer:
Definition of Poisson's ratio
Poisson's ratio is the ratio of transverse contraction strain to longitudinal extension strain in the direction of stretching force. Tensile deformation is considered positive and compressive deformation is considered negative. The definition of Poisson's ratio contains a minus sign so that normal materials have a positive ratio. Poisson's ratio, also called Poisson ratio or the Poisson coefficient, or coefficient de Poisson, is usually represented as a lower case Greek nu, n.
