Young's and modulus

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.
The tangent modulus of the initial, linear portion of a stress-strain curve is called Young's modulus.
In anisotropic materials, Young's modulus may have different values depending on the direction of the applied force with respect to the material's structure.
It is also commonly called the elastic modulus or modulus of elasticity, because Young's modulus is the most common elastic modulus used, but there are other elastic moduli measured, too, such as the bulk modulus and the shear modulus.

Young's and stress
Young's modulus is the ratio of stress, which has units of pressure, to strain, which is dimensionless ; therefore, Young's modulus has units of pressure.
Young's modulus, E, can be calculated by dividing the tensile stress by the tensile strain in the elastic ( initial, linear ) portion of the stress-strain curve:
Where is the applied stress, is a material constant called Young's modulus, and ε is the resulting strain.
This relationship only applies in the elastic range and indicates that the slope of the stress vs. strain curve can be used to find Young's modulus.
* Young's modulus (< var > E </ var >) describes tensile elasticity, or the tendency of an object to deform along an axis when opposing forces are applied along that axis ; it is defined as the ratio of tensile stress to tensile strain.
Mathematically, the modulus of resilience can be expressed by the product of the square of the yield stress divided by two times the Young's modulus.
where E is the Young's modulus, ν is Poisson's ratio, and K < sub > I </ sub > is the stress intensity factor in mode I. Irwin also showed that the strain energy release rate of a planar crack in a linear elastic body can be expressed in terms of the mode I, mode II ( sliding mode ), and mode III ( tearing mode ) stress intensity factors for the most general loading conditions.
Other moduli describe the material's response ( strain ) to other kinds of stress: the shear modulus describes the response to shear, and Young's modulus describes the response to linear stress.
The amount a material springs back is equal to Young's modulus for the material from the final stress.
