Welding wave on the contact spot of solids

摘要: Abstract In this paper the theoretical model of adhesion between clean solid surfaces is presented. Material behaviour described by hydrodynamic equations for viscous liquid and Gruneisen equation state. This approach quite suitable quantitative analysis mechanical processes running under high pressures. The states that growth a bonded area can occur in regime self-propagating welding wave (WW). WW originates at any active point where initial bonding takes place further moves velocity U ww ∼ γ / η ( surface energy viscosity material). According to presented plays key role adhesion.
