Analysis of a class of dynamic unilateral contact problems with friction for viscoelastic bodiesal variational formulations for the problems. Penalized formulations are investigated by using an abstract existence and uniqueness result. Several estimates on the penalized solutions are established which allow to pass to the limit and to prove the existence of solutions for these dynamic unilateral contact problems with friction.

Sthenic incompatibilities in rigid bodies motioniscontinuities. Velocity discontinuities may result either from an obstacle which makes impossible to compute the acceleration: this is a . or from the impossibility to compute the reaction forces: this is a .. We describe two examples: the Klein and Painlevé sthenic incompatibilities.

,Digital Television — a First Summary,. The MFC formulation of contact is based on the single gap vector, instead of two vectors (slip and stick one). The curved contact surface is defined in a parametric form, thus enabling finite deformations and a Lagrangian definition of contact.

The quadrilateral parametric contact element based on the moving friction cone formulation. The MFC formulation of contact is based on the single gap vector, instead of two vectors (slip and stick one). The curved contact surface is defined in a parametric form, thus enabling finite deformations and a Lagrangian definition of contact.

A study of symbolic description, numerical efficiency and accuracy of 2D and 3D contact formulationst), their finite element coding, and running of some benchmark problems in an objective way. This has been achieved by using a symbolic approach to derivation of formulas and automatic code generation.

Mortar-based surface-to-surface contact algorithms in large deformation solid mechanicsthat the spatial smoothing provided by mortar contact operators lends considerably more robustness than more traditional, node-to-surface approaches. Issues associated with efficient searching in the surface-to-surface framework are discussed, and some examples are summarized which demonstrate the effectiveness of the approach.

3D beam-to-beam contact within coupled electromechanical fields: a finite element modelrea is varying according to the beamto- beam angle, being circular only in the case of perpendicular beams. This variation of the shape is taken into account too. The problem is semi-coupled: the mechanical field influences the electric one because of the dependence of the voltage distribution on the contact area.
