We investigate hp-stabilization for variational inequalities and boundaryelement methods based on the approach introduced by Barbosa and Hughes forfinite elements. Convergence of a stabilized mixed boundary element method isshown for unilateral frictional contact problems for the Lame equation. Withoutstabilization, this may not converge because the inf-sup constant need not bebounded away from zero for natural discretizations, even for fixed h and p.Both a priori and a posteriori error estimates are presented in the case ofTresca friction, for discretizations based on Bernstein orGauss-Lobatto-Lagrange polynomials as test and trial functions. We alsoconsider an extension of the a posteriori estimate to Coulomb friction.Numerical experiments underline our theoretical results.
