WebbPoisson's ratio is an elastic constant defined as the ratio of thelateral contraction to the elongation in the infinitesimal uniaxialextension of a homogeneous isotropic body. In a viscoelastic materialPoisson's ratio is a function of time (or frequency) that depends on thetime regime chosen to elicit it. WebbPoisson, a French mathematician, determined that when a body is pulled in one direction, it gets compressed in the other perpendicular directions. Poisson’s ratio is defined as the ratio of the lateral strain to the longitudinal strain. it is generally denoted by the symbol µ. This is more like a mathematical formula.
