Youngs Modulus

The modulus of elasticity for a variety of common materials

Description

The modulus of elasticity defines the relationship between uniformly distributed normal stress \inline  \sigma_x and the resulting normal strain \inline  \varepsilon_x, i.e

Typical values include:
MaterialE (GPa)
Wood11
Aluminium69
Brass103-124
Titanium105-120
Iron190-210
Tungsten400-410
Silicon Carbide450
Diamond1050-1200

In structures the Young's modulus has importance in calculated the deflection or extension of beams due to applied loads, enabling an induced stress to be converted into a strain. As strain is defined as the (change of length)/(original length), then the movement of the structural member can be calculated.
