Pullout of a Rigid Insert Adhesively Bonded to an Elastic Half Plane

Abstract The problem considered here is that of a finite, rigid insert partially embedded in and adhesively bonded to an elastic half plane. Two distinct problems are investigated: the shear pullout of the insert without rotation, which takes into account the adhesive's resistance to shear deformation, and an opening problem which incorporates the adhesive's resistance to normal deformation. This latter problem assumes the presence of an edge crack in the half plane subjected to opening pressure which equals in magnitude the normal stress distribution due to the pullout problem. These mixed boundary value problems are governed by singular integral or integrodifferential equations. Numerical results are obtained via a technique introduced by Gerasoulis and Srivastav. Several important physical quantities are calculated, such as the shear and normal stress distributions along the bonded interface, and the crack opening displacements.
