Poisson's Ratio - Longitudinal Strain and Lateral Strain

It is the ratio of transverse contraction strain to longitudinal extension strain, in the direction of stretching force. There can be a stress and strain relation which is generated with the application of force on a body. For tensile deformation, Poisson’s ratio is positive and for compressive deformation it is negative, as in, negative Poisson ratio suggests that the material will exhibit a positive strain in the transverse direction, even though the longitudinal strain is positive as well. For most materials, the value of Poisson’s ratio lies in the range, 0 to 0.5.

We at BYJU’S strongly believe that a spirit of learning and understanding can only be inculcated when the student is curious, and that curiosity can be brought about by creative and effective teaching. It is this approach that makes our lectures so successful and gives our students an edge over their counterparts.
