Damping capacity of materials and its effect on the dynamic behavior of structures. Review

Damping is very important when studying the vibrations of bridge structures. A distinction is made between structural damping and damping due to internal friction in the material. The damping ability of the material allows it to absorb energy for irreversible processes during its cyclic deformation....
