One describes the total algorithm of resolution here employed. The integration of the relations of behavior itself is described in the documents [R5.03….] and [R7.01….], (for example [R5.03.02] for elastoplasticity), to which one will be able to refer for more details. For calculations in great geometrical transformations, one will be able to consult for example the document [R5.03.20] on nonlinear elasticity in great displacements, or the documents [R5.03.21], [R5.03.22] on the thermoelastoplasticity with isotropic work hardening. For the contact friction, there exist three documents: [R5.03.50] on the discrete formulation of the contact/friction, [R5.03.52] for the hybrid formulation by elements of contact/friction, and [R5.03.53] on the contact in great slips with method XFEM. For all that relates to piloting, it is necessary to refer to the document [R5.03.80]. Warning : The translation process used on this website is a "Machine Translation".
