Abstract: We study the adhesive contact between an rigid parabolic indenter and a half-space the elastic modulus of which is a power function of depth. A diagram is presented that shows the areas corresponding to a stable solution of the contact problem for high gradient exponents. It is shown that the adhesive contact between materials with a high gradient index is not destroyed when they are removed to any distance from each other.
Keywords: adhesion, contact radius, gradient media, indentation, Poisson's ratio.
