What is Poisson’s Ratio?
Poisson’s ratio is the ratio of the amount of transversal expansion to the amount of axial compression for small values of these changes.
Poisson Ratio Definition
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 length of the object. It gives an idea about the strength of a material.
Poisson’s Ratio
Poisson’s Ratio is the negative ratio of transversal strain or lateral strain to the longitudinal strain of a material under stress. When a material particularly a rubber-like material undergoes stress the deformation is not limited to only one direction, rather it happens along both transversal and longitudinal directions. In this situation, material scientists are curious to know the ratio of transversal and longitudinal deformation that occurred in the object to know about the strength of the material.
