Mechanics of rupture
=======================


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


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
