Modelling fiber pull-out in heterogenous fibrous composites

To be able to properly describe the failure of heterogeneous fibrous composites, we have to take into account the material behavior of every constituent. In the case of short fiber reinforced concrete (FRC), we deal with concrete, steel fibers and the bond- slip between them. Since the bond-slip along the concrete-fiber interface has a global representation, and is spanning more than one finite element, the chosen description is based on the extended finite element (XFEM) representation.
