Unilateral contact with Coulomb friction and uncertain input data. (English) Zbl 1049.49007
Summary: A quasivariational inequality (QVI) in $$R^d$$, $$d = 2, 3$$, with perturbed input data is solved by means of a worst scenario (anti-optimization) approach, using a stability result for the solution set of perturbed QVI-problems. The theory is applied to the dual finite element formulation of the Signorini problem with Coulomb friction and uncertain coefficients of stress-strain law, friction, and loading.
