An elastic constant named after British physicist Thomas Young (1773 to 1829) that is the ratio of longitudinal stress to longitudinal strain and is symbolized by E. It can be expressed mathematically as follows: E = (F/A) / (ΔL/L), where E = Young's modulus F = longitudinal force A = area F/A = longitudinal stress ΔL = change in length L = or [..]

Young's modulus, also known as the tensile modulus, is a measure of the stiffness of an elastic material and is a quantity used to characterize materials. It is defined as the ratio of the uniaxi [..]

The ratio of stress to strain in a solid.

(physics) The coefficient of elasticity of a solid; the rate of change of stress with strain.

Same as modulus of elasticity.

See Modulus of Elasticity. [Return to Glossary] [Z]

Elastic modulus of a solid sample, i.e., the ratio of stress in a sample to applied strain. For practical purposes, Young's modulus is equal to the inverse of the appropriate "s" constant.

Unit stress divided by unit deformation, specified as a constant.

Numerical expression indicating the measure of stiffness in a material. It is defined by the ratio of stress in a unit area of substance to the resulting deformation (strain). This allows the Behavior [..]

Elastic modulus applied to a stretched wire or to a rod under tension or compression. The ratio of the stress to the strain.

(E) The relationship between stress and strain in an elastic material. For engineering purposes, the ratio is considered constant within a certain range. An elastic material will return to its original shape once the stress is removed, and even materials such as concrete or glass are elastic to a degree. Once the yield stress is reached, plastic st [..]
