The friction force of a single elastomeric pillar on a smooth substrate is investigated under harmonic base excitation. Friction force variation is acquired for various excitation frequencies with a constant base acceleration where the pillar stays in stick regime. The peeling behavior of the pillar for different harmonic base displacements is discussed. The apparent work of adhesion is demonstrated via energy equilibrium at the contact interface. It was observed that a harmonic force may alter the interface adhesive nature, and the adhesion and friction coupling can be tuned via the excitation frequency.
