1. Mechanics of rupture#

1.1. XFEM#

Formulations:

  • Rubbing contact in small/large slides

  • Contactless

  • Axisymmetry

  • Large rotations

Features:

  • Multi-cracking

  • Junctions

  • Boundary conditions on knots XFEM

  • Pressure imposed on border XFEM

Scope of use:

  • Nonlinear behaviors

  • Thermo-mechanical

Crack propagation:

Possibility of multiple cracks as well as in 3D: PROPA_FISS

Post-treatments: iso-functionality principle between FEM and XFEM

Standard EF post-treatments:

  • Probability of breakage by cleavage: POST_BORDET

  • Extension to free mesh: POST_K1_K2_K3

  • POST_RCCM performance improvement

Post-treatments exploiting the XFEM framework:

  • Flat and non-flat cracks POST_K1_K2_K3

  • Extension to non-linear CALC_G

1.2. Cohesive models#

Features:

  • Crack initiation and propagation

  • Fatigue

  • Rubbing contact

  • Hydro-mechanical coupling

Fields of application:

  • Static and dynamic

  • Linear and non-linear

  • Fragile and ductile fracture

Family of models:

  • Attached elements

  • Discontinuous elements

  • Interface elements
