Reduction of the effective static coefficient of friction by shear ultrasound has been shown recently to be due to the partial lubrication of the solid–solid contact. Here, we study the effect of ultrasound perturbation on a multicontact interface at imposed drive velocity. We show that, together with the partial lubrication similar to the static case, ultrasound vibrations enhance structural aging and the emergence of stick–slip.
