Young's Modulus, Tensile Strength and Yield Strength Values for some Materials
Tensile Modulus  or Young's Modulus alt. Modulus of Elasticity  is a measure of stiffness of an elastic material. It is used to describe the elastic properties of objects like wires, rods or columns when they are stretched or compressed.
Tensile Modulus is defined as the
"ratio of stress (force per unit area) along an axis to strain (ratio of deformation over initial length) along that axis"
It can be used to predict the elongation or compression of an object as long as the stress is less than the yield strength of the material. More about the definitions below the table.

Strain  ε
Strain is the "deformation of a solid due to stress"  change in dimension divided by the original value of the dimension  and can be expressed as
ε = dL / L (1)
where
ε = strain (m/m, in/in)
dL = elongation or compression (offset) of object (m, in)
L = length of object (m, in)
Stress  σ
Stress is force per unit area and can be expressed as
σ = F / A (2)
where
σ = stress (N/m^{2}, lb/in^{2}, psi)
F = applied force (N, lb)
A = stress area of object (m^{2}, in^{2})
 tensile stress  stress that tends to stretch or lengthen the material  acts normal to the stressed area
 compressible stress  stress that tends to compress or shorten the material  acts normal to the stressed area
 shearing stress  stress that tends to shear the material  acts in plane to the stressed area at rightangles to compressible or tensile stress
Young's Modulus  Tensile Modulus, Modulus of Elasticity  E
Young's modulus can be expressed as
E = stress / strain
= σ / ε
= (F / A) / (dL / L) (3)
where
E = Young's Modulus of Elasticity (Pa, N/m^{2}, lb/in^{2}, psi)
 named after the 18thcentury English physician and physicist Thomas Young
Elasticity
Elasticity is a property of an object or material indicating how it will restore it to its original shape after distortion.
A spring is an example of an elastic object  when stretched, it exerts a restoring force which tends to bring it back to its original length. This restoring force is in general proportional to the stretch described by Hooke's Law.
Hooke's Law
It takes about twice as much force to stretch a spring twice as far. That linear dependence of displacement upon the stretching force is called Hooke's law and can be expressed as
F_{s} = k dL (4)
where
F_{s} = force in the spring (N)
k = spring constant (N/m)
dL = elongation of the spring (m)
Note that Hooke's Law can also be applied to materials undergoing three dimensional stress (triaxial loading).
Yield strength  σ_{y}
Yield strength is defined in engineering as the amount of stress (Yield point) that a material can undergo before moving from elastic deformation into plastic deformation.
 Yielding  a material deforms permanently
The Yield Point is in mild or mediumcarbon steel the stress at which a marked increase in deformation occurs without increase in load. In other steels and in nonferrous metals this phenomenon is not observed.
Ultimate Tensile Strength  σ_{u}
The Ultimate Tensile Strength  UTS  of a material is the limit stress at which the material actually breaks, with a sudden release of the stored elastic energy.
