6 most important 1 liners from the subject Steel

6 most important 1 liners from the subject Steel taken from the field Civil Engineering 1 Liners from the subject Steel Poisson's ratio "Poisson's ratio v" is a measure of the Poisson effect, which is the deformation (expansion or contraction) of material in directions perpendicular to the specific direction of loading in materials science and solid mechanics. The negative of the ratio of transverse strain to axial strain is Poisson's ratio. "v" is the amount of transversal elongation divided by the amount of axial compression for modest values of these changes. The Poisson's ratio of most materials is between 0.0 and 0.5. Poisson's ratio is around 0.5 in soft materials like rubber, where the bulk modulus is larger than the shear modulus. Poisson's ratio is approaching zero in open-cell polymer foams because the cells collapse with compression. The Poisson's ratios of several common solids are in the range of 0.2-0.3. Simeon Poisson,
