摘要

An analytical solution is presented for adhesive contact of a rigid disc inclusion embedded in a penny-shaped crack in a transversely isotropic piezoelectric material. By virtue of Hankel transforms and a method of potentials, the mixed boundary-value problem is formulated as dual and triple integral equations, which, in turn, are reduced to Fredholm integral equations. The results of primary interest to engineering applications, namely, the total indentation load, the total electric charge, and stress intensity factor at the tip of the crack are evaluated as integral equations in terms of dimensionless parameters. Finally, to reveal the efficacy of the proposed method and also to verify it, comparison is made with indentation solutions in transversely isotropic and isotropic media.
