| Popis: | When two surfaces are brought into contact and slide against each other, junctions are formed at the interface. The dynamics of formation, rupture and evolution of these junctions governs the tribological response of the macro-contact. Getting insight on the real behavior of these junctions is a challenging task. Theory states that contacts and asperities are continuously altered in two bodies due to applied pressure, which increases the number of active contacts. To addresses such altering interface conditions, wave propagation through tribological interface by means of the development of a numerical model is proposed. The proposed method is used to study and relate crucial parameters like stiffness, contact width, number of asperities that form a basis for an interface.
