Reliable solution of a Signorini contact problem with friction

Uncertain input data problems and the worst scenario method

“…• Unilateral contact with friction of elastic bodies: [16] Signorini problem with given friction, uncertain Lamé coefficients, slip limit; [30] Coulomb friction model, non-uniqueness, uncertain coefficients; [29] quasi-coupled thermoelasticity, uncertain conductivity, stress-strain law, loading, slip limits;…”

Unilateral contact of elastoplastic bodies with uncertain input data

“…[2] and the literature therein. On the other hand, only a few papers has been devoted to the contact problems with uncertain input data, such as material parameters and a loading -see [13][14][15] and [4] for the contact between elastic bodies.…”

Reliable Solution of a Unilateral Frictionless Contact Problem in Quasi-Coupled Thermo-Elasticity with Uncertain Input Data

“…By uncertain input data we mean physical coefficients, right-hand sides, etc., which cannot be determined uniquely but only in some intervals determined by the measurements. The reliable solution is defined as the worst among a set of possible solutions, and the degree of badness is measured by a criterion-functional (see [1]). The main aim of our contribution will be to find maximal values of this functional.…”
