Energy dissipation due to frictional slip under periodic loading in the presence of frictional coupling is investigated. The effects on energy dissipation of the relative phase between periodic loads along the normal and tangential directions are explored. The results show that, with increasing frictional coupling, the relative phase of the periodic loads approaches π/2 when maximum dissipation occurs. This behaviour is comparable to the uncoupled frictional case, for which maximum dissipation occurs at the relative phase of 0.6π. Analytical frictional dissipation is obtained for in the case of no relative phase between the loads.
