WebPoisson’s ratio is defined as the negative of the transverse strain ratio to lateral and axial strain. In the materials science, poisson’s ratio (\nu) implies the measure of the poisson effect and its value is the negative of the ratio of transverse strain to axial strain. Highlights of Poisson’s Ratio [Click Here for Sample Questions] WebWe attribute these negative Poisson's ratio behaviors to the special interaction of p z orbitals between the interfacial layers. Furthermore, we observed among them high-order elastic …
