We develop an efficient reduced basis method for the frictional contact problem formulated using Nitsche's method. We focus on the regime of small deformations and on Tresca friction. The key idea ensuring the computational efficiency of the method i

In this thesis, we investigate model reduction for parameter-dependent variational inequalities. First, we consider the case where the problem is formulated by a mixed method, where the challenge is that the reduced model must satisfy an inf-sup stab

We consider model reduction for linear variational inequalities with parameter-dependent constraints. We study the stability of the reduced problem in the context of a dualized formulation of the constraints using Lagrange multipliers. Our main resul
