Poisson's ratio, a key material property describing the relationship between axial and lateral strain in solid materials. Typical Poisson's ratio values for metals, polymers, ceramics, and more, along with practical applications in engineering and mechan
By definition, Poisson’s ratio is the negative ratio of transverse to axial strain [53]. In view of most solids, when a natural object is stretched axially, it will contract laterally. Poisson’s ratio is normally a positive value ranging between 0.25 and 0.33 [61,62]. In nature, just...

Poisson's ratioVolume strainIncompressibilityRubberThe controversy in the definition of Poisson's ratio (PR) as a material constant is discussed in this study. PR of an isotropic material is usually defined as the ratio, taken with the opposite sign, between its lateral and longitudinal strains ...
Definition Poisson’s ratio is the name given to a ratio of lateral strain to axial strain. Its recognition as a property of materials is attributed to Siméon-Denis Poisson (1781–1840), a French mathematician and student of Laplace. Uniaxial extension of a solid rod causes it not only to...

It is defined as "the ratio of shear stress to the displacement per unit sample length (shear strain)" . Modulus of Rigidity can be experimentally determined from the slope of a stress-strain curve created during tensile tests conducted on a sample of the material. Definition of Modulus of ...
The modulus of elasticity in tension, also known as Young's modulus E, is the ratio of stress to strain on the loading plane along the loading direction, Common sense (and the 2nd Law of Thermodynamics) indicates that a material under uniaxial tension must elongate in length. Therefore the...
