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 fl ux averaged over the period and directed from the gas into the condensed phase; this heat fl ux is compensated for with the dissipation of mechanical energy from the loading source. A possible infl uence of this
mechanism of dissipation on the heating of automobile tires is assessed. Possible methods of recording of this effect
are discussed.
