An example of a material with a large damping capacity is gray cast iron.
2.
Materials like brass and steel have small damping capacities allowing vibration energy to be transmitted through them without attenuation.
3.
Grey iron also has very good damping capacity and hence it is often used as the base for machine tool mountings.
4.
Good-quality natural granite is becoming more and more difficult to find, but has a higher damping capacity than cast iron.
5.
A large damping capacity is desirable for materials used in structures where unwanted vibrations are induced during operation such as machine tool bases or crankshafts.
6.
For example, metals in general exhibit yielding and plastic deformation, whereas most fiber-reinforced composites are corroding behavior, high damping capacity and low coefficients of thermal expansion.
