Theorie adhesion
WebbThe classical theory of contact focused primarily on non-adhesive contact where no tension force is allowed to occur within the contact area, i.e., contacting bodies can be separated without adhesion forces. Several analytical and numerical approaches have been used to solve contact problems that satisfy the no-adhesion condition. Webb1 jan. 2011 · This theory suggests that adhesion is developed through the interdiffusion of molecules in between the adhesive and the adherend. The diffusion theory is primarily …

WebbThe adsorption theory states that adhesion results from molecular contact between two materials and the surface forces that develop. A bond develops from the adsorption of adhesive molecules on the substrate and the resulting attractive forces, usually designated as secondary or van der Waals forces. Webb8 nov. 2024 · The theory proposed in [ 1 ], which is called “adhesion mechanics,” is based on the concept of the existence of the described contact layer between the adhesive and the substrate. The works devoted to the contact layer method in adhesion mechanics (at first the author called it a boundary layer) began in the Soviet Union in the early 1970s ...
