On the one hand, in the last few years, the community of computational mechanics has made significant improvements in the development of efficient and robust numerical methods to perform damage and fracture simulations (using non-local finite element formulations, cohesive zone models, phase-field, XFEM, thick level-set, or adaptive remeshing). On the other hand, concerning the material modeling side, Gurson's family models have shown their efficiency to correctly predict complex multiaxial ductile failure path, while, in the context of fatigue failure, new models have been developed to deal with anistropic damage and crack propagation in generalized plasticity. However, while the numerical approaches usually lack of phenomenological or physical basis, complex material models are usually identified using traditional FE solution processes. Thus, the main objective of this minisymposium is to share knowledge from the two worlds and benefit from the progress of each community in order to build more accurate and efficient numerical simulations that take into account the complexity of the material physics. 

The scope of the talks in this symposium can be related to:
- ductile failure and finite strain simulation of crack initiation and propagation
- thermo-mechanical fatigue and anisotropic damage modeling
- multiscale material behavior modeling of failure processes and related numerical techniques
- fatigue crack propagation model in multiaxial, anisothermal and generalized plasticity
- cohesive element, non-local or phase field simulation processes
- XFEM, GFEM, thick level-set or crack propagation with adaptive remeshing
- coupled experimental and numerical studies of failure process
- industrial applications with material modeling and numerical simulation
- etc.

Keywords: damage to fracture, crack propagation simulation, nonlinear material modeling, ductile and fatigue failure.
