Effect of adhesion on the frictionless receding contact between an elastic layer and a substrate

ABSTRACT

In the present work, adhesion has been incorporated in a model for receding contact between an elastic layer and a half plane under flat and parabolic punches. Based on the JKR model for adhesion and with the help of integral transformation, solution of the problem may be reduced to a system of singular integral equations. A numerical scheme has been proposed and verified. The effect of adhesion on contact size and the stresses has been demonstrated.
