This thesis is concerned with the solution of contact problems with advanced Coulomb friction in the 3D case using the finite element method. A Lagrange multiplier method modelling the contact traction is employed and the contact conditions are enforced in a weak sense leading to a surface-to-surface discretization. Here more precisely the dual mortar method is used allowing for a static condensation of the additional variables in the system before solving without loosing the optimality of the solution. The discrete contact inequalities are embedded in the algebraic system using a semi-smooth Newton method handling all system non-linearities, geometrical, material and contact within one iteration loop. In contrast to other research in th...
