Spring material
In the past, cork was usually used as a springy material, the springiness of which was due to compression and relaxation of the trapped air. The spring materials that are coming to the fore today are steel and rubber.
Rubber as a building material
Rubber has special properties compared to other building materials. The elongation can be more than 1,000% in certain cases and for the most part in the elastic range. Metals, on the other hand, have very small strain values below the elastic limit.
Design aspects
With hard rubber you can increase the strain a little. The connection of rubber with metal is not a weak point and stronger than the rubber itself.
Principle Constellations
In principle, elastic intermediate layers, i.e. vibration dampers, are installed in practice for two different reasons: Practical considerations and protective considerations.
