Abstract This work proposes a novel multi-phase-field formulation to characterize the distinct damage mechanisms
and quasi-brittle fracture behaviors in FRC. The phase field driving forces for each failure mechanisms are
first defined based on an anisotropic energy split scheme. Then, the PF degradation functions pertinent to
each failure mode are properly defined with corresponding material fracture quantities, which enables the
derivation of embedded Hashin failure criteria for fiber- and matrix failures respectively. Furthermore, the
material damaged stiffness is redefined within the anisotropic CDM framework, and a linear CZM is
mathematically derived for each of the typical failure mechanisms. Finally, the model… More >
