Among the most important and widely used mechanical components are springs, in which the elastic properties of materials are exploited for energy storage and conversion. No mechanical or mechatronic system can function without springs, regardless of their design.

Intrinsic in the behaviour of springs, and especially in their use, is the ability to be able to withstand continuous elastic deformations, which momentarily change their constructive dimension at the moment of their application;

Springs must also be able to absorb large amounts of elastic energy, which must be released when the external force ceases to be applied.
