On the other hand, if a damping material has a too large viscous proportion, this can lead to excessive viscous heating, and therefore, to an even destructive degree of deformation finally. In this case, too much deformation energy would be transformed into heat, more than can be simultaneously stored or transported through the material to the outside. As a consequence, further supply of deformation energy might lead to partial or even complete destruction, i. e., to softening or even to the break of the material.

Example: Car tires, and lost deformation energy

Tire air pressure being 0.2/0.4/0.6 bar too low reduces the working life of the tires by 10/30/45 %. Further negative effects are increased rolling resistance, changed driving characteristics of the vehicle for the worse, extended braking distance, and increased fuel consumption [5.16].
