Effects of temperature on friction: Constitutive equations and experiments with quartz gouge Academic Article uri icon

abstract

  • A state-variable constitutive relation that can describe the dependence of friction on temperature at or near steady state conditions is presented. The relation is derived from existing state-variable relations used to describe velocity dependence and the assumption that the micromechanisms of friction are thermally activated and follow an Arrhenius relationship. Experiments indicate that (1) an abrupt increase in temperature induces a transient friction response similar to that induced by a step decrease in velocity, (2) the transient friction response is relatively symmetric for steps up and steps down in temperature, and (3) the characteristic slip distance for friction to evolve to steady state after step changes in temperature is the same as after step changes in velocity. -from Author
