Poisson's ratio Source: Poisson's ratio of a material defines the ratio of transverse strain (x direction) to the axial strain (y direction). In materials science and solid mechanics, Poisson's ratio (symbol:

Young's modulus Source: Young's modulus (or the Young modulus) is a mechanical property of solid materials that measures the tensile or compressive stiffness when the force is applied lengthwise. It is
