On a Thermodynamic Mechanism of Dissipation of Mechanical Energy in Porous Elastomers as Applied to the Problem of Heating of Automobile Tires

It has been shown that in the case of cyclic mechanical loads on a porous elastomer there are regimes in which irreversible processes of heat transfer between the gas and the elastomer are responsible for the appearance of a nonzero heat flux averaged over the period and directed from the gas into t...

Description
Summary:It has been shown that in the case of cyclic mechanical loads on a porous elastomer there are regimes in which irreversible processes of heat transfer between the gas and the elastomer are responsible for the appearance of a nonzero heat flux averaged over the period and directed from the gas into the condensed phase; this heat flux is compensated for with the dissipation of mechanical energy from the loading source. A possible influence of this mechanism of dissipation on the heating of automobile tires is assessed. Possible methods of recording of this effect are discussed.
