Méthode de Newton généralisée en mécanique du contact

• Section 4: the analysis is done on the Signorini problem with Coulomb friction in finite dimension, using an arbitrary finite element method and a particular discretization of

In Section 1 we present the setting and notations for the problem under consideration: large deformation contact with Coulomb friction and possibly self–contact. In Section 2

It is expected that the difference between a classical model and crystal plasticity can be still larger if two rough surfaces are considered instead, since the way

Even when using stable monotone finite element discretisation of the frictionless contact problem (that we may write in a mixed form introducing mortar elements to represent

The complete contact law (Signorini conditions + Coulomb friction laws) is a com- plex non smooth dissipative law including three statuses (no contact, contact with sti- cking

Dans ce travail nous pr´ esentons quelques consid´ erations sur la mod´ elisation et l’ana- lyse variationnelle des mod` eles math´ ematiques d´ ecrivant le contact entre un corps
