Description
The modulus of elasticity defines the relationship between uniformly distributed normal stress and the resulting normal strain
, i.e
(1)
Typical values include:
| Material | E (GPa) |
| Wood | 11 |
| Aluminium | 69 |
| Brass | 103-124 |
| Titanium | 105-120 |
| Iron | 190-210 |
| Tungsten | 400-410 |
| Silicon Carbide | 450 |
| Diamond | 1050-1200 |
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.
